libjpeg version: 6b
http://www.ijg.org/
libjpeg is a bit old and parts are out-of-date, and there is a bug, so it needs some patching. In a Terminal type:
$ cd path_to_folder_containing_libjpeg_source_tar_gz
$ tar -zxf jpegsrc.v6b.tar.gz
Then, replace ltconfig and ltmain.sh with these patched versions. They contain a couple Mac OS X patches to the version of libtool in the jpeg source. Also, download this patch for the makefile and unzip it into the source folder.
Then continue:
$ cd jpeg-6b
$ cp -f /usr/share/libtool/config.* .
$ patch makefile.cfg makefile.cfg.patch
$ ./configure --enable-shared --enable-static
$ make
$ sudo make install
