I'm trying to emerge mythtv on my currently updated System and I'm always getting the following error regardless of which version of mythtv I'm trying to build (Is there any guide I could use for installing mythtv (Maybe I'm missing some preparations I currently don't know of).

That's why GCC 4.4 is masked. ;) This seems to be your problem. http://blog.flameeyes.eu/2009/07/02/how-_not_-to-fix-gcc-4-4-bugs
Actually it's glibc, sorry. In any case, this is a duplicate of bug #272358.
Please use at least mythtv-0.21_p20877 or newer when using glibc 2.10 or higher.
