It'll be a bug in cabal-install. It's passing a flag to a Setup.hs that
was built with an older version of the Cabal lib that does not
understand a new flag. What's not obvious to me is why it's passing the
flag at all. I'd expect it only to do that if you passed --distpref when
you invoke cabal-install.
I've filed a ticket so we do not forget. If you have any more details,
add them to the ticket.
Actually, could you run the failing command with -v3 and show us the
output (including the full command used). I'm interested in what value
of distpref is being passed as that might give us a clue as to where it
is coming from.
