I saw that, realized I didn't change directory at all and wasn't
really sure how to proceed. It did help me narrow done the cause to
something directly in the test suite though.

Sure thing:

    1 danking at spock # cabal --version
    cabal-install version 1.20.0.2
    using version 1.20.0.0 of the Cabal library

    danking at spock # ghc --version
    The Glorious Glasgow Haskell Compilation System, version 7.6.3

Upon seeing this version information, I tried changing my build-depends to
depend on Cabal 1.20 or greater, but I still get the error.
