Importing in ghci

Hello, I just started using GHCI and I am having trouble importing modules except for these in the "imports/std" directory. I am using windows, and my GHC installation directory is "d:/ghc/ghc-5.02.1". I tried starting ghci with the -i option: ghci -I"d:/ghc/ghc-5.02.1" to no avail... Tried it with quotes, without quotes, tried relative path, no help. 'ghc-pkg -l' reports that the module that I import is indeed in an installed package, and as far as I understand as long as the module is in an installed package, GHC should be happy. What am I missing? Thanks konst
