Cabal-188.8.131.52 is registered and built with ghc-6.8.3 - I installed it
with Cabal seconds before running this example.
My cabal.exe comes from the hackage website, the binary you put up
some time ago. I guess that is probably the issue.

Meh. Custom build scripts are brittle and evil - in my particular case
the custom build script was trivial so adding build-type:Simple fixes
everything. However, I'd like to know (before I push a change) that
build-type:Simple will work out the box with the Cabal that got
installed with ghc-6.8.3. So that means figuring out what Cabal
ghc-6.8.3 shipped with, and which Cabal can cope with
build-type:Simple - is there any way to figure that out in general,
and what is the answer in this specific case?
