<p>I'll give another recommendation for virthualenv, I've taken to using it for just about everything I do because it keeps my repo clean. It's slightly inefficient in that you can end up with many copies of common libraries, not to mention a full ghc install for every project, but HD space is cheap, and it saves you time trying to resolve library conflicts down the line.</p>

If you want to test something, there are several packages for doing<br>
that. cabal-dev and virthualenv both set up repositories in your<br>
current directory, allowing you to cabal install packages willy nilly<br>
without affecting your global package database. I personally prefer<br>
virthualenv (not the spelling), but both are very good programs.<br>
