Attached is a new ebuild for Bit.Trip Runner, "an arcade-style rhythm game developed by Gaijin Games". Ebuild is pretty standard fare for a Humble Indie Bundle release, with one rather notable exception: it's linked against a version GLIBC only provided with >=GCC 4.6. Since that's still 'unstable' in Gentoo, I found a workaround.
Jamestown, also included in the same bundle, also requires this version of GLIBC, but unlike Bit.Trip Runner it actually bundles it with the game. So, I give you today's Terrible/ugly/dirty/stupid/don't-try-this-at-home hack to work-around need for GCC 4.6:
if use jamestown; then
Obviously this is not even remotely a preferred solution, but the last time I unmasked GCC 4.6 on my system it brought KDE to it's knees (seems to have some bad interaction with nepomuk), so I'd prefer to hold off for now. If it's included in portage, the whole Jamestown workaround should be dropped, but I'm leaving it included here just for reference for anyone else that may find themselves in a similar situation.

rev bump. New revision no longer requires GCC 4.6 (yay!), so I removed all of the jamestown library hackery.
