This should be fixed in an upcoming revision (within a few days).  Here's the local commit info:

commit 7f5771a13aec5a8a724e0d0c9d761f5a82e74af0
Author: Manuel Rommel <[e-mail]>

    Fix compilation on PPC with some recent GCCs

[Comment 2 darkshikari 2010-11-11 16:39:52 UTC]

Fix is now committed.

[Comment 3 Alex Buell 2011-01-25 22:40:03 UTC]

Please see bug 352073, it seems to be still broken with latest portage sync on PPC. I certainly don't see -flax-vector-conversion used when compiling.
