Can't Build 64-bit Tomcat Connector Module (mod_jk)

Question

I've been using the Tomcat Connector Module on my server so all requests can be logged by Apache, I only need to open port 80 on the firewall, and sites that use jsp with other technologies look more cohesive to the user.
In the past when a new version of the module was released I'd just download the source, unzip it, build it and instal it. Following the included instructions, "for the impatient Apache admins," I used:
./configure --with-apxs=/usr/sbin/apxs
to configure the build, then "make" and "sudo make install" to build and install the module.
This has always worked well (except it always installed the module in the wrong directory, which I never corrected because I liked to test the new module before I got rid of the old one), and when I moved to an Intel Mac, it continued to work. All the Apple-provided modules were universal binaries, but the i386 modules I built worked fine.
Now, with Leopard, we have a new, 64-bit Apache 2. I had been looking forward to working with Apache 2, and 64-bit is nice too, right? But now that it's here I'm not so sure.
My first disillusionment was that, when I downloaded the mod_jk source and built it using the same procedure I had been using, Apache refused to load the module, saying it had the wrong architecture. I checked the provided modules to see what architecture it wanted, and they were all universal binaries with four architectures, which didn't really narrow it down too much, but since I could rule out the ppc and ppc64 architectures, and the "wrong" one I built was i386, that left x86_64 as the only possibility.
Since I barely know what I'm doing, I'm not about to try anything crazy like building a universal binary (although I did try to follow this tutorial, but it didn't work for this project and his instructions didn't provide enough detail for me to even begin to figure out why), but I can't even figure out how to build a 64-bit binary.
I do have Xcode 3.0, so I should have the ability to build 64-bit binaries, and I have the new Java 1.6.0, which is also supposed to be 64-bit, so I should be race-ready, but when I run the configure script, specifying which Java version to use and which architecture to build:
./configure --with-apxs=/usr/sbin/apxs --with-arch-type=x86_64 --with-java-home=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Hom e
I still end up with an i386 binary when the smoke clears, and in the log is a warning:
configure: WARNING: you should use --build, --host, --target
I'd be happy to do that if I had a clue what values to specify for them. Does anybody want to guess? Here's what it keeps taking for default values:
checking build system type... i386-apple-darwin9.2.2
checking host system type... i386-apple-darwin9.2.2
checking target system type... i386-apple-darwin9.2.2
I have a feeling I can't just substitute x86_64 for i386 (i.e. x86_64-apple-darwin9.2.2). The "x86_64-apple-darwin" part might be right, but I don't know about the 9.2.2. I've poked around the filesystem and gotten thoroughly confused. There seem to be all kinds of headers and compilers for i386 and x86_64 and something called i686, which seems to be related to x86_64 somehow, but I have no idea how to point the makefile to the right ones. I don't even know how or why it seems to be perfectly capable of finding everything it needs to build for i386 without my help, and even when I try to mislead it by suggesting I might want it to build for x86_64, it still unerringly finds all the i386 stuff and builds the module with them.
Since no one seems to provide Mac OS binaries of anything, it would be really nice to understand how to do this. I might even want to go crazy and build a 64-bit PostgreSQL or something like that, but if I can't even build a simple Apache module anymore, my hopes are fading.
If anybody is somehow clued-in on how all this stuff works, I'd really appreciate a brain-dump.
Thanks.

Thank you, that works for me too!
At first I was worried because, when I ran configure it said:
checking build system type... i386-apple-darwin9.3.0
checking host system type... i386-apple-darwin9.3.0
checking target system type... i386-apple-darwin9.3.0
But I went ahead and ran make anyway, and here's what I ended up with:
apache-2.0/mod_jk.so: Mach-O 64-bit bundle x86_64
which I could install and test. It even works!
Where did you find this information? I did a lot of digging too, but I must have been digging in the wrong places. I always like to go back to the source and see what else I can learn. Maybe then I can take another run at building a universal binary.
