[proaudio] problem with portage and zynaddsubfx

[Dominique Michel <dominique.michel@xxxxxxxxxxxx>]

I get a strange problem with portage today. First, I done an sync, and get the
problem described here: https://bugs.gentoo.org/show_bug.cgi?id=147010

The fix did it. I rerun the sync so at portage finish its job. But now when I
run 

emerge --update --deep --newuse -vp world

portage want to downgrade zynaddsubfx. 

# emerge --update --deep --newuse -vp world

These are the packages that would be merged, in order:

I try to remove the header in the overlay's ebuild (They are for a 2.2.1-r2 version), and
re digest the ebuild, but it didn't help. If I mask the 2.2.1-r2 version, it didn't find the overlay's versions.

I try to upgrade portage to the ~x86 version, but it didn't help either.

If I try:
# emerge -vp =zynaddsubfx-2.2.1-r5

These are the packages that would be merged, in order:

Another issue, but not related to my problem, is at qsampler-9999.ebuild have ~arch keyword when it should be -*
