Can I install jpeg6b and jpeg at the same time?

Great.

What port installed /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/popplerqt4.so? Nothing in MacPorts should be installing into /Library/Frameworks (unless you've changed your frameworks_dir to /Library/Frameworks—have you?)

The jpeg6b port was replaced by the jpeg port a long time ago; it's gone.

The openjpeg port, which installed /opt/local/lib/libopenjpeg.1.dylib, should be rebuilt so that it uses the jpeg port instead.

sudo port -n upgrade --force openjpeg
