Created attachment 921548 [details] fc20.src.rpm used successfully in mock Please Branch nas for EPEL 7
nas is (another) one of those largely legacy bits of software that probably would not be all that beneficial to include in epel-7. If there's something that requires this, I'd recommend to disable nas support (if it is optional). Otherwise, we can reconsider.
Here again we have a tree of depends. mpg123 - RPMFusion Bug 3321 needs nas to build mplayer - RPMFusion Bug 3322 needs mpg123 to build MyhtTV needs mplayer for install So we'll have to see what the developers do/need when branching el7.
Pretty sure the nas support is optional in all those pieces, I'd recommend simply not including it. If I'm in error, please correct me (and feel free to re-open this bug)
