panic when compiling again

haskelldb 0.10 doesn't build under ghc 6.10.1. I download it with:

cabal fetch

Then unpack it and use the attached modified .cabal file to enable a build with:

cabal build

It should build. Do a

cabal install

It will then attempt to rebuild, but will fail with the error:

[18 of 25] Compiling Database.HaskellDB.Database ( src/Database/HaskellDB/Database.hs, dist/build/Database/HaskellDB/Database.o )
ghc: panic! (the 'impossible' happened)
  (GHC version 6.10.1 for i386-apple-darwin):
	idInfo r{tv adJo} [tv]

However, if you clean and then install it will succeed

cabal clean
cabal install

ghc 6.10.1 doesn't like something about the intermediate files left over from the cabal build step.
