> I'm having issues with PIL 1.1.6p2 (the release version) not finding its
JPEG libraries. These are located in /usr/lib64 on CentOS 5.5 / OpenSuse,
however the default library path only considers /usr/lib. Adding
/usr/lib64 as a library path fixes the problem in my stand-alone PIL
build. I'm not quite sure how to patch the setup.py in SAGE to add this
path by default.
Well, we should just check if `/usr/lib64` (and `/usr/local/lib64`) exist,
and if so, add these '''instead of''' `/usr/lib` etc., unless
`realpath("/usr/lib64") == realpath("/usr/lib")`. (We may also check we're
really on a 64-bit system, too, though the presence of `/usr/lib64` should
normally indicate that.)
Note that on other (64-bit) Linuces (e.g. Debian), `/usr/lib64` is a
symbolic link to `/usr/lib`, while on Fedora etc. `/usr/lib` is a synonym
of `/usr/lib32` (like on 32-bit systems).
