/usr/bin/ld: unknown flag: -compatibility_version

Question

Hi, I have a fresh reinstall of OSX on my revision two MacBook Pro and I installed the developer tools 2.4.1. I now have a problem that has halted all of my development.
I cannot compile any of my unix apps. I run ./configure, it succeeds and my compile will even succeed, up until when it goes to link it and I get the following error:
/usr/bin/ld: unknown flag: -compatibility_version
Here is the full line when it's building the program (in this case, libexpat, but it also does this for other apps, such as apache):
/bin/sh ./libtool --silent --mode=link gcc -I./lib -I. -g -O2 -Wall -Wmissing-prototypes -Wstrict-prototypes -fexceptions  -DHAVE_EXPAT_CONFIG_H -no-undefined -version-info 6:2:5 -rpath /usr/local/lib  -o libexpat.la lib/xmlparse.lo lib/xmltok.lo lib/xmlrole.lo
/usr/bin/ld: unknown flag: -compatibility_version
collect2: ld returned 1 exit status
make: *** [libexpat.la] Error 1
Does anyone have any idea on what needs to be done to fix this? I would greatly appreciate it.

Upon lots of tweaking, I got it to compile. I'm not sure what I did that fixed it, but now I've got a new issue.
If you've got any ideas, please let me know:
