After a portupgrade last night /usr/ports/multimedia/mplayer would not
build so this morning I went to rebuild XFree and it failed with:

I'm going to give that a try.

BTW, mplayer fails while looking for X11:

Checking for byte order ... Little Endian
Checking for shared postprocess lib ... no
Checking for GUI ... yes

Error: X11 support required for GUI compilation
