I'm on Fedora Core 6 (64 bit)
after "yum install libjpeg-devel" I have downloaded and built PIL. It gives the message:
--- JPEG support ok
Looks like JPEG built okay, but when running selftest.py:
IOError: decoder jpeg not available
Why would it appear to have built correctly, but fail the selftest?
Turns out this gets solved by completely removing the installed versions of PIL and starting the build again from scratch.
Building Python PIL for JPEG looks okay, but fails the selftest
