Strictly speaking, the explicit conflict with openmotif-devel is bad in general. Why? Because first of all, what has happened at Fedora is that we've replaced OpenMotif with Lesstif. And hence we need a mechanism to get rid of the obsolete packages in user's installation, which have been dropped from the distribution and which are not updated anymore. Even if the main "openmotif" package does not conflict with the main "lesstif" package, it remains installed, is available to dlopen and other forms of linking. Lesstif ships the same SONAMEs, just with lower versions. The *.so symlinks in the -devel package may point to the wrong package when lesstif, openmotif and old openmotif-devel are installed. Worse than that, an upgrade blocks lesstif-devel from replacing openmotif-devel. This is not just inconvenient, it is ugly. It makes users, who perform an upgrade, think "WTF?".

Ought to be: Obsoletes: openmotif <= 2.3.0-0.2.1 Obsoletes: openmotif-devel <= 2.3.0-0.2.1 I like it, FWIW. ;-) > but there may not be another solution.
