So, now that I've got all the libraries installed, the compile fails like this:

Building lambdabot-4.0...
[13 of 91] Compiling Lib.Parser       ( Lib/Parser.hs, dist/build/lambdabot/lambdabot-tmp/Lib/Parser.o )

     Module `Language.Haskell.Syntax' does not export `as_name'

     Module `Language.Haskell.Syntax' does not export `qualified_name'

     Module `Language.Haskell.Syntax' does not export `hiding_name'

     Module `Language.Haskell.Syntax' does not export `minus_name'

     Module `Language.Haskell.Syntax' does not export `pling_name'

I'm using the latest darcs pull of lambdabot along with ghc 6.6.1.  Anyone have any ideas?

Thanks in advance for all the help,
