Can't get PHP with GD / libjpeg to work

Question

I'm totally frustrated, I tried compiling PHP 5.2.6 with GD and JPEG/PNG support on my Dual 2 GHz PowerPC G5 since yesterday (installed the latest XCode version) but without success so far. I also did all necessary steps like recompiling apache2, libjpeg and libpng. I found lots of tutorials but none of them worked out. PNG support works fine, here's the info from phpinfo()
GD Support enabled
GD Version bundled (2.0.34 compatible)
GIF Read Support enabled
GIF Create Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled
But whenever I use --with-jpeg-dir=/usr/local/lib /that's the dir I compiled libjpeg to) when configuring php I get the following errors when executing the "make" command:
lt -liconv -liodbc -lmysqlclient -lldap -llber -liconv -liconv -lfreetype -lX11 -lXpm -lpng -lz -ljpeg -lssl -lcrypto -lcurl -lz -lssl -lcrypto -lm -lxml2 -lz -licucore -lm -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lcurl -lssl -lcrypto -lz -lxml2 -lz -licucore -lm -lmysqlclient -lz -lm -liodbc -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxslt -lxml2 -lz -licucore -lm -o libs/libphp5.bundle && cp libs/libphp5.bundle libs/libphp5.so

Can anyone help me? Maybe I need special CFLAGS for my machine? Thanks in advance.

I got the jpeg source files from http://www.ijg.org/files/and compiled it according to some tutorials I found on the net. I also installed it using the port command (used --with-jpeg-dir=/opt/local for php then), but whatever I did and whatever configuration I used I always get the same error.
/opt huh? Why am I not surprised? Your first step should be to purge all traces of whatever "port" software you were using and delete any software you installed with it. If you don't want to do that, you'll have to contact them (fink or MacPorts/DarwinPorts or whatever they are now) for support. The port packages do work and seem to work well for the software they provide. The evidence I have seen indicates that if they don't provide the port, it won't work. Be prepared for very strange and unsolvable problems when compiling non-ports software using ports tools. Plus, you can't really ask for help from the non-ports community, because all that non-ports software works fine for us.
PS: Sorry if I sound a bit harsh. I've just seen too many of these postings. At least I have located the culprit - Apple!. That information is over five years old. I'm going to file a bug report against it.
But I will try to help with what I can for now...
Tried it with
env MACOSXDEPLOYMENTTARGET=10.5 CFLAGS="-O -g -arch ppc -arch i386" LDFLAGS="-arch ppc -arch i386"
./configure -prefix=/usr -sysconfdir=/etc -localstatedir=/var -mandir=/usr/share/man -disable-dependency-tracking
and without the env command as well
Unless you are distributing the software, you shouldn't need to include the cross compilation options. However, when linking several of these projects together (as in PHP) you do need to match the compilation options for all the code that is linked together. Use whatever settings you used when you built PHP.
then
cp /usr/share/libtool/config.sub .
cp /usr/share/libtool/config.guess .
./configure --enable-shared --enable-static
make
sudo make install
sudo ranlib /usr/local/lib/libjpeg.a
It seems that libjpeg hasn't been updated in 10 years, so these instructions look OK, more or less. Try "--disable-static" instead of "--enable-static". If that fails, leave them both off and try to link against the default static libraries.
