I solved the problem adding to the linker,  /usr/bin/c++ -o medm blah ... -lca -lCom -lXm -lXt -lXmu ... the library -lXft . I can now save my displays without a crash. If you compile openmotif from source, you should be aware that Xft lives in its own library. Perhaps this should be noted in the MEDM README.

FWIW, on my systems, "ldd" on the libXm.so shared library reports that it 
depends on libXft, and the dynamic linker takes care of that.  I don't know
why the dylib you've build doesn't carry that same information, but you
can double check the dependencies with "/usr/bin/otool," so I read.  If it
doesn't list libXft as a dependency then something is busted in the build. 
Not sure how to fix it.  But if it *does* list libXft as a dependency and just
can't resolve it, that's another matter.

It would be interesting to see how Fink builds openmotif3 and how that differs
from how you're doing it.
