link problem under macosx

[Christian Maeder]

Hi,

after installing
http://lambda.galois.com/hp-tmp/2010.2.0.0/haskell-platform-2010.2.0.0.i386.dmg
and various more libraries using cabal, we get the following linker
error below.

A simple hello program compiles and links fine and uses
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version
7.0.0) as shown by "otool -L".

Does someone have an explanation or solution?

Cheers Christian
