Your Header-Files seem to be missing. These should be somewhere under
/usr/include on RedHat (if I remember this correctly).

There oughta be a "libjpeg-devel.rpm" on your RedHat CDs, find and
install it. That should solve your problem.
Otherwise you'd have to compile & install libjpeg by hand ....

Cheers,

Michael
