Replying to [comment:40 Koen]:
> It's because the PIL setup.py is trying to be smart: it creates its own
list of search paths for includes & libs, and when it cannot find
jpeglib.h in the includes or libjpeg.so in the libraries search paths, it
will disable its own JPEG support. However, it does not check a common
place for 64-bit Linuxes (which are not Debian-based), so right now it is
too eager in disabling JPEG support.
> Note that SciPy uses PIL to read JPEG images, so not having it working
is quite annoying.
Yep. If we don't fix that (here), you could still create symbolic links in
`SAGE_LOCAL/{include,lib}`; then PIL should find them as well.
(If we build binary distributions (with e.g. JPEG support enabled), we
have to manually ''copy'' the system's respective libraries and headers to
`SAGE_LOCAL/...` anyway.)
