The mplayer ebuild supports the 'xinerama' USE flag (use-enable xinerama). However, invoking emerge -pv mplayer does not show the flag. The reason is probably that the flag is not listed in the IUSE variable in the ebuild although it could and should be listed. Reproducible: Always Steps to Reproduce: 1.USE="xinerama" emerge -pv mplayer 2. 3.

Proposed fix: add 'xinerama' to IUSE variable in ebuild (trivial).
I'll take care of it in the next day or so, thank you :)
Thanks for quick reaction, the bug had caused some confusion.
In-Cvs....
