Then, it might be an fvwm bug. Report it at fvwm-workers@fvwm.org, which is
the dev mailing list for fvwm, so it can be tracked and fixed.

Mplayer has a version number because it's a snapshot with a given date. The fvwm is
a live ebuild, which means that each time you emerge it, it download the latest code
from cvs. So, if you emerge it again the next week, it will automatically update your
fvwm if something has changed in cvs.

Cvs/svn/git and similar ebuilds are always numbered as 9999. That's why.

It doesn't. You need to keep trak of the live ebuilds manually. There's an unofficial
script called live-ebuilds-update or something like that. You can search the gentoo forums.
I saw it around there but can't give you a link right now.

Gentoo doesn't add too much stuff. Just a couple of patches. But it would  help if you can
reproduce your problem with a vanilla build of fvwm. Without patches. So we can confirm that
it's an fvwm problem.

With my fvwm cvs ebuild you can do this, to get a vanilla build:

USE="-extras -translucency" emerge =fvwm-9999
