Packaging openmotif for rpmfusion

Hallo, I'm trying to create a openmotif package which I want to introduced into rpmfusiion. Unfortunately, I have the following issue: openmotif-devel and lesstif-devel can't been installed on the same system. But I can't remove lesstif-devel because mesa-libGLw-devel has a Requirement to lesstif-devel. So I would to ask, if we can to the following: 1.) Add a 'Provides: motif-devel' in lesstif-devel 2.) Rename the lesstif-devel dependencies in mesa-libGLw-devel into motif-devel. I will be glad for your feedback. Best Regards: Jochen Schmitt
