Description of problem: octave-3.0.0-6.fc9.x86 depends on /usr/lib64/libgfortran.so.1 but its RPM does not depend on compat-liboctave-41. a better solution would probably be to recompile against libocave-4.3.0 (if possible)
This should be fixed by octave-3.0.1-1.fc9, which is currently in updates-testing, and should soon be in updates.
