What's this?  There's no official PIL release named 1.1-2.  The
current version is 1.1.1.

PIL has been running on Alpha boxes since before it's first public
release.  The JPEG support works perfectly fine under tru64, and
on many other 64-bit systems.

Do you get the error message on "open", or when you're trying to
do things with the file?   (if open is successful, trying doing an
explicit load)

Have you tested more than one file?  (there's a sample file included
in the source distribution)

Maybe you have a broken compiler?

Oh, really?
