Before I install it (on on Mac OS X Lion) is there anything, manually, that I need to do in order to keep all of the cabal packages that I've installed, or are the reinstalled automatically?
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. -Brent
