Oh, I'd forgotten that GHC comes with Cabal.  Yes, I think rebuilding
should suffice.  I don't think GHC Breaks the previous cabal, though; I
think cabal always had this bug, and it always affected the network
package, but the conditional in question didn't actually need to fire
until base 4.3.1, which comes with GHC 7.0.2.

Also, cabal-install has a new upstream version as well, though I don't
think it affects this particular issue.
