Potentially. I'll look at using an external libjpeg6 first (because that's what
Debian and Fedora have, and they're the reasons for this change), then try 
with libjpeg8.

If they're close enough (which I believe they are - they're mostly
API-compatible), we could probably patch ioquake3 for libjpeg6 support until we
move to libjpeg8; it's better than having to patch it for system-libjpeg
support at all!
