Ug. I have a weird franken-install on my end, so "cabal install
cabal-dev" (or even just a "cabal unpack" "cabal configure") works
cleanly for me.

Maybe you could file a ticket with "cabal-dev" to ask what you need to
do to install on a fresh platform install, or ask on haskell-cafe.

Can you try upgrading "cabal-install" to see if the new solver handles
it better? I think the new version works with what is in the platform.
If you also get errors there might be ways to make it go ...
