 cabal install cabal-install-0.10.2 fails for me. The problem is that it
 depends on unix < 2.5 and versions of unix before 2.5 depend on base <
 4.4. But base 4.4 is selected very early on in the cabal install. Later
 versions of unix (i.e. 2.5.0.0) work with base < 4.5, so it seems like
 this issue could be fixed by releasing a new version of cabal-install that
 works with unix 2.5.

 Here is the output from cabal install cabal-install-0.10.2 -v3 --dry-run:
