[Xmonad] compiling problem

[Michael Vanier]

Hi everyone,

First off, thanks to everyone who's working on xmonad.  I'm an ion user 
and I'd love to have equivalent functionality implemented in a (*ahem*) 
better language.

I've been going through the procedure to install xmonad-0.1, and I 
successfully installed all the dependencies.  But the xmonad build fails 
thusly:

Preprocessing executables for xmonad-0.1...
Building xmonad-0.1...

XMonad.hs:27:7:
     Could not find module `System.Posix.Process':
       Use -v to see a list of the files searched for.

I'm running ghc-6.6 compiled from source on Debian Linux.  Any hints?

Mike
