[Haskell-iPhone] trying to run the examples

Tue Dec 27 14:56:08 CET 2011

Hi,
The issue about hidden packages can be solved by adding text to build depends in the cabal file. I added the latest version that could be compiled (0.11.0.8) but now this results.
I think I agree with you to wait for GHC 7.x for the iPhone.

I didn't, but I don't know that I should?
I read about visi as a new language for the iPad, well I haven't one, but still it looks nice and simple
