I spoke with the listed maintainer, Brendan Low <lostlogic@gentoo.org>, and he no longer has the time to maintain the ebuild. The unmasked version is a a version behind current, as well. Reproducible: Always Steps to Reproduce: 1. 2. 3.
This build is now assigned to the sound herd and all bugs are fixed currently. :)
excellent, thanks guys. btw, vorbis-tools 1.0.1 works just fine, unmask it :P
