As far as I know, sbuild's internal resolver tries to satisfy the first alternative. But the problem in this case is caused by sbuild trying to satisfy *both* alternative dependencies instead of ignoring everything but the first alternative. sbuild should only install libversion-perl instead of both libversion-perl and perl 5.12.
