[proaudio] some errors in the ebuilds?! - or maybe a wrong setting here

[Harald Gutmann <harald.gutmann@xxxxxxx>]

i synced with the proaudio overlay today, and tried to make a system update, 
but emerge claims about some ebuilds from the overlay.
has anyone of you an indea, what the problem is/could be?

here is the output form the emerge command:
benchvice hg87 # emerge -pvuND world

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