I'm guessing the OP was actually referring to 'virthualenv', which was recently released and works with Haskell (but is similar to virtualenv for python). It seems that virthualenv lets you set up independent "environments" including sandboxed builds and custom versions of GHC, etc., and switch between them.
Ah! Thanks, I wasn't aware of virthualenv. So far, it looks cool. I have a bit of a knee-jerk reaction to the statefull approach it takes (heavily tweaking your active shell environment to do the sandboxing), but it does do things that cabal-dev doesn't. Playing with it more now. --Rogan
