Hello, I attempted to build cvs head but it died with the following error:

Any idea what changed? http://www.haskell.org/pipermail/cvs-ghc/2003-December/019309.html http://www.haskell.org/pipermail/cvs-ghc/2003-December/019313.html I am enjoying template haskell so far (despites the bugs), and the changes since 6.0 are pretty nice! I find the naming scheme in THSyntax.hs in 6.2 much easier to read than in 6.0. Thanks! Jeremy Shaw.
