Howdy, I'm back to using GHC-iphone... I'm merging stuff I've been working on into an iPad app. I'm using certain libraries like Parsec 3 (is Parsec 3 GHC 7 only?) When I do a try to install Parsec: dpp@oldboy:~/proj/LispHaskellIPad$ iphone-cabal install parsec Warning: Error parsing config file /Users/dpp/.cabal/config:77: Parse of field 'libsubdir' failed (paths with spaces must use Haskell String syntax): Warning: Using default configuration.

Any pointers or hints to make iphone-cabal work for parsec? Also, a note to the developers on the list... don't upgrade to Lion... Xcode 4 on Lion seems to not work at all with any of the Haskell stuff (iphone or GHC 7). Thanks, David
