I've installed gnuplot using Mac Ports on a machine running Mac OS X 10.7. The installation exited without any errors or even warnings, however when I try to run it the following shows up:
dyld: Library not loaded: /opt/local/lib/libfontconfig.1.dylib Referenced from: /opt/local/lib/libgd.2.dylib Reason: Incompatible library version: libgd.2.dylib requires version 7.0.0 or later, but libfontconfig.1.dylib provides version 6.0.0 Trace/BPT trap: 5
Any suggestions what to do? Is there a quick and easy fix for such problems?
