Ok, got the sources from CVS, and cloned the "configure" invocation as
the build for FC3 does it...  Then made a couple of minor tweaks (below).
Here's what I got:

- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We 
can't and
  won't help unless you provide this information when reporting a 
possible bug.
