Please update Murmur to the latest Version 1.2.8 Reproducible: Always Steps to Reproduce: 1
Created attachment 387218 [details, diff] murmur-1.2.8.ebuild Just changed the package number. Things seemed to compile, although if there were any changes between versions, this script does not take that into account.
According to the Mumble page, 1.2.7 and 1.2.8 are just bug fixes and security updates: http://wiki.mumble.info/wiki/1.2.7 http://wiki.mumble.info/wiki/1.2.8 I have tested the ebuild on my end and have not had any issues with it so far.
Sorry that it took a while, fixed in CVS now.
