I really feel uneasy about xmbind not being with the libraries, but
if it helps, no problem. An alternative would be to rename one of the
xmbind program (likely for the init script and the man page) to 
lesstif-xmbind or openmotif-xmbind.

Yep, this seems unavoidable. And, I beleive, right!

For -devel that would be nice, but for main I think it would be
wrong since there is no ABI compatibility.

In fact there should even be a way to make package compiled
against lesstif require lesstif and for packages compiled 
against openmotif require openmotif. Indeed the usual way
to have library dependencies (using soname) doesn't work
well here, as the same soname is associated with binary 
incompatible libraries. Having a simple

Requires: openmotif
or 
Requires: lesstif

should be enough, since the dynamical linker may get it wrong
as they have the same soname, but then the library names 
would be the same and they would conflict. 

As long as the lesstif soname (and library name) differs from 
the openmotif soname this could be enough.

Does this seems right?
