cabal sdist broken on OS X

[tibbe]

The latest released version of cabal-install generates an sdist correctly:

$ cabal sdist -v3
Warning: Cannot run preprocessors. Run 'configure' command first.

I found the problem by accident; I had installed some "random" version of cabal-install from HEAD as I was testing out the new cabal bench feature.

This bug only occurs when you build cabal-install-0.10 against Cabal-1.12, something which is explicitly prevented by the version constraints in the cabal-install-0.10 cabal file. That is, you only get this bug if you edit the .cabal file to relax the constraints. If you do that, you're welcome to keep both pieces. Alternatively, build Cabal & cabal-install head.

Just adding before I forget that folks seeing this may be following instructions for getting GHC on MacOS X 10.7  https://gist.github.com/1169332 which say to relax the dependencies. Somebody with a round tuit should probably add instructions to get cabal-install head

@kowey: I'm currently updating that (my) guide with instructions as to how to build Cabal 1.10. If people here think it's better to add instructions on how to build Cabal and cabal-install HEAD I'm happy to do that instead.
