Run the configure step again with -v3, we should be able to see in the
log exactly what string we got back from ghc.

Also, to make sure you're using the version of the Cabal library you
expect, try:

ghc --make Setup.hs -package Cabal-1.2.3.0
./Setup configure

That way we know what we're using, even if you happen to have multiple
versions of Cabal installed or if runhaskell happens to point at hugs
rather than ghc.
