For what it's worth, I got this while manually bootstrapping
haskell-platform onto a GHC HEAD build and it turned out to be a complex
interaction between unix, network, bytestring, and base versions.  Cabal's
ability to report such things is limited, to say the least.  (More
specifically:  I'd have to go through the bootstrap again to get the full
details, but Cabal somehow managed to conclude that it needed a version of
base with bytestring in it at the same time that it needed a modern version
of base, and this was triggered somehow by newer versions of network which
have subsumed the old network-bytestring package.  IIRC it actually made a
certain twisted sense at the time.)
