It's pretty straight forward to get it going, at least with GHC 6.4.1.
From memory you'll get the ambiguous errors above for 4 functions in 
AFRPUtilities which are now in Control.Arrow and some problems with modules 
moving into the heirarchical module namespace.  Perhaps IO and Random?

Just delete the four arrow functions from AFRPUtilities and use the in-builts 
from Control.Arrow and import the hierarchical modules.
Oh, and watch your tab size, there is a blend of spaces and tabs at the start 
of lines.

Or I can send you a copy of the code I've got here.
