Yeah, that's kindof ugly.  The only foolproof way I can think of
handling this, is to have compatibility symlinks in the mkfontdir
package in /usr/X11R6/bin.

If anyone has alternative ideas for a reasonable solution though,
I'm open to ideas.  If nothing else comes up as a viable solution
however, I'll probably stick some backward compatible symlinks into
the packaging prior to FC5 though, as I think we do need to cover
this at least for a few OS releases.  Also, since FC is the basis
for RHEL, the back-compat stuff probably needs to stick around
longer than I'd prefer to have it stick around.  That can be handled
separately for RHEL though too..

Suggestions appreciated.
TIA
