This function should be defined in the core, which you built and installed 
first, right?

Even if you did that right, your issue could happen because multiple 
versions of the same library installed can be installed, and also because 
contrib is allowed to accept core versions >=0.8. So perhaps contrib is 
being built with the 0.8 core library (or possibly the actual 0.8.1 library 
which cannot be distinguished from the 0.8.1 version that the current darcs 
pretends to be).

Use, with the addition of --user and --global flags, depending on the 
output of ghc-pkg list:

ghc-pkg list
ghc-pkg hide xmonad-0.8 # optionally specifying a version

And maybe then the most recent core will be used
