There is a bug in media-sound/moc-2.5.0_alpha4_p20110428 if net-misc/curl-7.21.4 is compiled with thread support (the thread flag has been made default recently). cURL author provided a fix for moc (http://curl.haxx.se/mail/lib-2011-05/0155.html) that has been submitted and merged to moc upstream (http://moc.daper.net/node/242). It would be good idea to apply the patch to current moc ebuilds to resolve this bug until upstream release new version (actually upstream does not release new versions so often).

It might be worth just making a new snapshot release since this should be done with a revision bump anyway.

This snapshot fixes the cURL problem, however brings another. It cannot play applicaton/ogg streams because since commit r2356, the list of decoders for this MIME type has been made empty. Attempt to play such stream results in `Format not supported' error message. According upstream (http://moc.daper.net/node/433#comment-4491), this is intentional (currently). User must `PreferredDecoders = application/ogg(vorbis)' or `PreferredDecoders = application/ogg(*)' in mocp configuration file to get Ogg/Vorbis streams working again. I think it would be nice to einfo this issue in the ebuild.
