Isaac just removed the old cabal-install. the new cabal-install (old cabal-get) should be able to install packages locally:
cabal-install install foo/bar.tgz
cabal-install install foo/foo.cabal bar/bar.cabal
A bonus point would be if it figured out the dependencies (cabal-get already does this) and installed them in the correct order.

cabal-get is dead, and cabal-install can install. There doesn't seem to be a bug here.
