A much better way would be to modify the ebuild to do what you want, 
then copy it to a local overlay. Portage will use your overlay in 
preference to the portage tree. You just have to then watch out for 
newer versions to hit the tree which will supercede your custom ebuild, 
and modify those new versions similarly.

There's an environment variable EXTRA_ECONF intended for *users* to add 
extra configure options when emerging, but I have heard bad things 
about using this. Don't know the details, perhaps someone else who does 
will post in response.

Finally, you could just mask out mplayer entirely and build it from 
source using the default DESTDIR of /usr/local. It's not a complete 
unistall solution, but at least it doesn't collide with portage's 
installs in /usr/

man 5 ebuild has lots of info on this topic
