TTBOMK, this will fail also if there is a slot change.  For instance,
with the recent autoconf-2.69 move from :0 to :2.69, dependency
resolution would have resulted softblock, thus removing :0 and then
merging :2.69 automatically. with a --nodeps, :2.69 would attempt to
merge without removing :0 for this package, resulting in an emerge failure.
