The ebuild media-tv/mythtv-0.19_p9163-r1 checks for mysql support in the installed packaged 'qt'. Now that qt-4* is in portage, it should check that qt-3* uses 'mysql'. Expected: (1) If installed qt-3* has mysql USE, then mythtv should detect it as such. (2) Mythtv should depend on qt-3* only. It does not compile against qt-4*. Actual: (1) If qt-3* is installed with mysql USE, and qt-4* installed without mysql USE, then mythtv ebuild still aborts. (2) Mythtv ebuild depends on qt >= 3.3, when it should be qt >= 3.3 and < 4.0 .
This has already been fixed. Please emerge --sync.
