Problem building HXQ on Mac OS 10.5.5

Hi,

I'm new to haskell and wonted to start tinkering a bit with this  
language, specifically with HXQ. I have installed ghc with macports.

Now while building HXQ I get the following error:

Main.hs:20:9:
     Not in scope: type constructor or class `C.SomeException'

Unfortunately I'm also new to Mac OS X. Before I developed on Linux.
It would be great, if someone could give me a hint.

Thanks,
Tobias

PS: Below the details

~$ cabal install hxq

I think you should be able to build it if you manually download the
.tar.gz file from Hackage and then type:

runghc Setup configure
runghc Setup build
runghc Setup install

The Control.Exception module was changed in ghc-6.10.1 (specifically,
in the base-4 package).  HXQ's code assumes that when compiling with
ghc-6.10 you're always using base-4; however, that compiler also comes
with base-3.0.3 which is a compatibility package providing the same
interface as previous versions of ghc.  The 'cabal install' program
tries to be helpful and selects base-3.0.3 (since HXQ does not specify
which to use), causing the above error.
