First check that you have not inadvertently added any virtual packages in 
/var/lib/portage/world.  If so remove them, portage will bring them back if 
needed.  Then use:

emerge -uaNDv world
emerge --depclean -p -v
emerge @preserved-rebuild -p
revdep-rebuild -v -- -a

perl-cleaner is also a good to run anytime portage updates any perl packages.

Have a look at 'man qdepends' for direct and reverse dependencies of different 
packages.  In your case jpeg seems to be borked, so investigate jpeg and jpeg 
libraries with the above tools to see what may be causing the problem.  It 
could be that a package is in world that shouldn't be, or it could be that you 
have some USE flag set that forces portage into a knot.

HTH.
