Comment(by simonmar):

 Most packages build without actually ''running'' any Haskell code, Happy
 is slightly unusual in that it has a `Setup.hs` file that is built and run
 during installation.  `pandoc` and `texmath` have the same property (look
 for `Build-type: Custom` in their `.cabal` files).

 Still, it is strange that you can use `cabal-install` to install Happy
 manually.

 I suspect there are some inconsistent packages somewhere, and when you use
 `cabal-install` manually it is avoiding the problematic packages.  What
 happens if you rename `.ghc`?
