Summary pretty well hits it. musepack-tools src downloads so far have eluded my googling, so the package is at the moment worthless. url anyone?
Created attachment 32274 [details] Ebuild with updated SRC_URI This ebuild fixes the problem. It should be noted, however, that MPC has now gotten a new homepage and gone LGPL! Congratulations to everybody involved!
By the way, this ebuild is still not entirely correct. Musepack requires the "oss" USE flag, and/or possibly "esd". It does not compile with only USE="alsa".
Yeah, the site hosting the source is (temporarely?) down. As for use flags, it does declare both oss and esd, doesn't it? Without having those it will issue error on unpack stage with further instructions.
the download of the source should direct to http://www.saunalahti.fi/cse/seed/downloads/linux/encoder/mppenc-linux-libc6-1.15r.zip
or rather to http://xmixahlx.dyndns.org/audio/files/linux/musepack/mpcsv7-src-1.15r.tar.gz
fixed in cvs.
