Yes, haddock 2.4.1 (the most recent release) bombs on Data.TypeLevel.Num.Aliases.
In Haddock 2.4.0 we switched from using the compilation mode of the GHC API to a mode which does only typchecking. This broke Template Haskell support: http://trac.haskell.org/haddock/ticket/68 The problem is fixed in Haddock 2.4.2 which will be released with GHC 6.10.2. David
