PIL JPEG mis-step

[darkblueB]

I got the Python Imaging Library from source, built and installed, on
Ubuntu 7.10, not realizing I could run a self-test first. libjpeg is
on the machine, but was not detected.. so no JPG encoder. I got the
dev-libjpg and rebuilt PIL. The self-test now shows JPG support.

but running setup.py install again seems to succeed, but still no
JPG :-(

fix ideas appreciated
