     I suggest Guy's solution to this problem might be the best. 

     "openmotif-devel" was un-installed by an update (ALL) to today's current Fedora Core 6 OS, which I did recently.  Probably because of the conflict with lesstif which was installed (just guessing).

     My Fedora Core 6 had not been updated since my original installation last November when I installed every Core 6 option.

I found that it was straightforward to make medm work under lesstif.  
The following
patch may suffice:

         if(items[i].accelerator) {

             XtVaSetValues(items[i].widget,
               XmNaccelerator, items[i].accelerator,
               XmNacceleratorText, str,


Basically, the XmStringCreateLocalized function gets called with a NULL
argument from time to time.  This is technically undefined according 
to the
API, but allowed by openmotif and causes lesstif to segfault.  The patch
simply substitutes an empty string for the NULL where necessary.

A caveat:  I'm not a heavy medm user so YMMV....
