I'm new with Haskell and have trouble with its package.
I want to import System.Random but
Could not find module `System.Random'
Then I tried to import System but
Could not find module `System'.
It is a member of the hidden package `haskell98-2.0.0.0'.
I tried to search this problem, but those solutions still don't work.
As this said, I tried to install cabal on my Mac OS X using MacPort, but
Error: The following dependencies were not installed: ghc Error: Status 1 encountered during processing.
I have installed Haskell Platform and can use ghci in command-line. GHCi, version 7.2.1
Then I tried to use ghc-pkg expose haskell98-2.0.0.0 as this one says.
But this time, I can't even run ghci.
Top level:
Ambiguous interface for `Prelude':
it was found in multiple packages: base haskell98-2.0.0.0
So, what can I do without using cabal?
