PyQt4-4.5.1 ebuild was removed from the portage tree over the weekend.
I had only that specific version unmasked (IIRC kde4 dependencies?),
and ran into a similar(?) situation yesterday. Maybe you hit the same?
(Similar situation == portage surprises and wants to downgrade PyQt4
to 4.4.4-something.)
No worries, IIRC I just unmasked 4.5.2 and everything has been smiles
and sunshine again afterward.
