I'll upload the ebuild in a bit assuming I can work the kinks out ;)
Created attachment 59047 [details] A crappy ebuild, mostly copying from the sphinx2 ebuild ;) I didn't know exactly what do 'dodoc' mostly taking whatever was there from the Sphinx2 build. I noticed it put a lot of stuff in /usr/share/doc anyhow. Anyway, this emerges fine for me, I dropped all keywords save ~x86. Note, I tested both +alsa and -alsa.
*** Bug 100533 has been marked as a duplicate of this bug. ***
If no one is going to pick it up thats cool, I know sound is overloaded right now anyway and the ebuild will stay in bugzi.
other QA things while i'm looking though. inherit should be the first line. gnuconfig eclass isn't used - omit omit src_unpack - this is the default behaviour in bug 100533 you've put a make check in src_install. This isn't needed as src_test does this automaticly, The LICENCE looks weird having BSD and as-is. I hate dealing with licences that are weird but probably BSD is sufficient.
