In 1.4_beta, some ebuilds, such as lbreakout2 and tuxracer are, during configuration giving the error message during configuration that SDL_MIXER is not found. The documentation for lbreakout2 says that this means the development package is not installed. The result is that the ebuild is compiled without audio. Identical results on 3 installations. Suggestions on IRC indicate that this should be filed against libsdl rather than gcc 3.2 Looking at the bug report mentioned in the Changelog (bug #3762) I tried downgrading, however had the same results. It does work without problem in Gentoo 1.2 using gcc 2.95. It's apparently not a sound issue as other things, such as lbreakout work without problem. Problem is reproduced consistently whether using lbreakout2 ebuild or downloading source for lbreakout2 from Sourceforge.
See bug 6888. Had I seen that one I probably wouldn't have filed this one.
