not the 'prettiest', but this has worked for me:
wget http://www.ijg.org/files/jpegsrc.v6b.tar.gz
gnutar zxf /usr/ports/jpegsrc.v6b.tar.gz
cd /usr/ports/jpeg-6b
unsetenv CFLAGS CPPFLAGS CXX CXXFLAGS LDFLAGS LDDLFLAGS LD_PREBIND LINGUAS LC_ALL LANG
setenv LDFLAGS "-ldl"
rm -rf /usr/local/lib/libjpeg*
cp /usr/local/share/libtool/ltmain.sh .
cp /usr/local/share/libtool/config.guess .
cp /usr/local/share/libtool/config.sub .
# USE THE LTCONFIG INCLUDED WITH THE FINK DISTRO ... WHY? IT WORKS ...
cp /sw/lib/fink/update/ltconfig .
mkdir -p /usr/local/bin/
mkdir -p /usr/local/man/man1/
mkdir -p /usr/local/include/
mkdir -p /usr/local/lib/
# make distclean
./configure \
- --prefix=/usr/local \
- --enable-shared --enable-static
make
make install
make install-lib
ls -ald /usr/local/lib/libjpeg*
