I understand that you might drop the ImageMagick requirement which
would make this issue moot.  Meanwhile I developed a patch (attached)
which allows octave-forge to build on Fedora.  Perhaps it could be
applied now, then it will be fixed if you end up generating an interim
octave-forge-2009MMDD release?

The problem turned out to be the pre-processor flag
(i.e. "-Wp,-fopenmp" works), not the linker flag, so to ensure all
flags get passed correctly, my patch escapes both using "-Wp," and
"-Wl," respectively.  So the patch should make the compilation of the
module more robust on all systems.
