Neither. If you install a new version of GHC, you must reinstall any
cabal packages you want, because they must be recompiled with the new
GHC.
Note that cabal-install does have a special command
cabal install world
which (IIUC) is supposed to help automate this process, although I
can't vouch for it since I have never tried it.

I installed it on Windows 7 and then re-installed a lot of packages, it
looks ok with exception of some warnings (-fglasgow-exts, for example).
But the package stream-fusion could not compile, because it's cabal file
has an illegal ghc option: -fno-method-sharing. I commented this out and
then everything worked fine.
