(From Adrian Hey) Here's the error:

This will probably reproduce it, but it's not quite what I did:
1 - darcs get http://darcs.haskell.org/packages/collections-ghc6.6/
2 - Edit collections.cabal so you have:
{{{build-depends: base >= 2.0, QuickCheck, bytestring, containers,
array}}}
3 - runghc Setup.hs configure
4 - runghc Setup.hs build
