[Haskell-beginners] Just started working with Haskell. Need some help

[David McBride]

Look at the .cabal file for the package you are trying to compile.  It will
list all the dependencies.  If there is no cabal file you are out of luck.
You'll just have to find all the dependencies yourself.

I will say it is a bit easier to find libraries via hayoo (
http://holumbus.fh-wedel.de/hayoo/hayoo.html) than in straight google.
