Re: [Haskell-cafe] mtl and transformers

Hi,

when I cabal-installed the iteratee package, the transformers package was also installed as a dependency.

Now when I run applications that import Control.Monad.Transformers I get this:

Could not find module `Control.Monad.Trans': it was found in multiple packages: transformers-0.1.4.0 mtl-1.1.0.2

Another solution is to build your applications using Cabal and specify your dependency on mtl in the cabal file. HTH, Martijn.
