 I was trying to install regex-dfa.  I should mention that I have library
 profiling enabled in my cabal-install config.  So when a dependency claims
 to be hidden I usually just reinstall it and everything works.

 Here, I tried that and base showed up as a dependency (shouldn't I have
 the profiled version of base already?), and when I tried to cabal install
 base, I get a funny error.

 Transcript below (note that I've selected 1.6.0.2 from the version drop
 down, but my version is actually 1.6.0.3, but isn't in the list).  My GHC
 version is also not in the lits.  I have 6.10.4.

 {{{
 $ cabal --version
 cabal-install version 0.6.2
 using version 1.6.0.3 of the Cabal library

 $ cabal install regex-dfa
