Hi, I was reviewing old code and the same happened to me. A simpler (and cleaner) solution is: 1. Remove dependency on haskell98 2. Remove "import System" 3. Add the following two imports: import System.Environment import System.Exit No need to import prelude explicitly. The program should compile without problems this way.

Hi,  I am not the maintainer.

 AFAIK, haskell98 is only used to import System in Test.hs.

 You should be able to remove the dependency on haskell98 from the cabal file and install the library without problems. In order to test it, move Test.hs to a temp directory after installing the library, add the following import to that file:

import "base" Prelude

And compile with:

ghc --make Test.hs -package haskell98 -XPackageImports -XNoImplicitPrelude

Cheers, Ivan.

Hi,

Marko Lauronens email address from the package is invalid, so I'm trying to reach him this way.

pngload doesn't compile with ghc >= 7.2 because of it's dependency to base and haskell98.

Greetings, Daniel
