Comment (by dmwit):

 According to ghc-pkg, the only two packages that are hidden are
 vector-0.11.0.0 (in the user database) and ghc-7.10.2 (in the global
 database). Neither of those appear in the dependency tree of
 vector-0.10.12.3, which is:

 }}}

 I also ran ghc-pkg check just to make sure no packages were broken; the
 only report is an unrelated complaint about haddocks for the nats package.
