Version 1.8.1 has been released for a while. http://savannah.nongnu.org/forum/forum.php?forum_id=8057 Copying the ebuild from 1.8.0 seems to work for me.
Copying the ebuild works for me too, and is the only way to get support for some chips.
I dropped a possible ebuild in with no keywords for users to test. Best I can do for now.
tested, in ~arch
It works well here. I've removed my local chages (1.8.1 ebuild mostly), and emerged this one. I can compile all my projects (which i couldn't with 1.8.0). Thanks!
