This time the install died on HJScript:
********** [ 2 of 26] Compiling HJScript.Monad ( src/HJScript/Monad.hs, dist/build/HJScript/Monad.o )
src/HJScript/Monad.hs:51:10: A pattern match on a GADT requires -XGADTs In the pattern: EmptyBlock In the definition of `mappend': mappend EmptyBlock b = b In the instance declaration for `Monoid (Block ())' cabal: Error: some packages failed to install: HJScript-0.4.5 failed during the building phase. The exception was: ExitFailure 1 **********
I have no idea what to do next, so I'll probably bring this particular issue up on the Happstack list next.
This one I can help with. You need to modify the .cabal file for HJScript slightly. To do this: cabal unpack HJScript cd HJScript-0.4.5 ${EDITOR} HJScript.cabal And then add 'GADTs' to the 'Extensions:' list. Antoine
