Created attachment 80878 [details] emerge.log Here's my log from compiling mythtv with USE="backendonly"
Did you really read the warning about USE=backendonly ? :)
It doesn't work always, it's hit or miss. And that's according to upstream. There's no support for it by me or by upstream. If you want to use it like that it's up to you to make it work. You can then submit the patches and make it work for more people.
Point to having something that no one wants to touch? :)
