I emerged quake3-bin with USE="cdinstall", everything went fine until I tried
to run the game:

You also need to install quake3-data with USE=cdinstall.

This is INVALID, but I am adding a check to quake3-bin to force usage of
cdinstall on quake3-data if it is enabled in quake3-bin, so it is also FIXED. 
:P

There's no way of knowing that the "cdinstall" flag is required . . . can
something be added to the ebuild?

cdinstall makes it sound like you're installing from the cd, but games that
rely on quake3-bin, such as urbanterror, aren't supposed to need the CD version
of the game at all. Yet emerging them without setting "cdinstall" for the deps
results in failure at runtime. Be nice if the ebuild set +cdinstall via EAPI2
or some other explanatory message was added to the ebuild.

it's a use dep now with EAPI=2
