As Summary, emerge -C xorg-x11 and try and build,.. `emerge mythtv` fails with /usr/lib/gcc/i686-pc-linux-gnu/3.4.4/../../../../i686-pc-linux-gnu/bin/ld: warning: libXcursor.so.1, needed by /usr/qt/3/lib/libqt-mt.so, not found (try using -rpath or -rpath-link) /usr/qt/3/lib/libqt-mt.so: undefined reference to `XcursorLibraryLoadCursor' x11-libs/libXcursor appears to solve this issue.
Uhm, it's QT3 that links to it, and it already depends on libXcursor. You more like need to run emerge -uD world to bring in the dependencies you've unmerged by mistake.
so it's o.k. to say emerge -Du world when upgrading from <=x11-xorg-6.9 to > x11-xorg-6.9? and mythtv required the latter.
I guess this one will be useful: http://www.gentoo.org/proj/en/desktop/x/x11/modular-x-howto.xml

As said above, not mythtv bug (plus qt already depends on libXcursor). Closing.
