I was having a problem installing jpeg-6b on my PPC with 10.5.2. I found this recipe on ​http://wiki.roboteducation.org/MacOSX_Setup :

Install libraries to save and send your images as jpeg.

If you have fink or macports try installing libjpeg that way (e.g. fink install libjpeg libjpeg-bin libjpeg-shlibs) Otherwise follow these instructions to install libjpeg from source.

1. download libjpeg ​http://www.ijg.org/files/jpegsrc.v6b.tar.gz
2. untar that (tar -xvzf jpegsrc.v6b.tar.gz)
3. cd jpeg-6b/
4. ln -s which glibtool ./libtool
5. export MACOSX_DEPLOYMENT_TARGET=10.5 (for tcsh or csh use setenv

MAXOSX_DEPLOYMENT_TARGET 10.4)

6. ./configure --enable-shared --prefix=/usr/local/
7. if /usr/local/ /usr/local/include /usr/local/lib don't exist create them:
   1. sudo mkdir /usr/local/
   2. sudo mkdir /usr/local/lib/
   3. sudo mkdir /usr/local/include/
8. make
9. sudo make install-lib

10. sudo make install-headers
11. export MACOSX_DEPLOYMENT_TARGET=

In point 4 i used:

ln -s /usr/bin/glibtool libtool
