Hi, with http://darcs.haskell.org/~ghc/dist/6.12.1rc1/ghc-6.12.0.20091010-i386-unknow... installed (under /local/maeder/) I get the following "internal Haddock or GHC error". I have no file /local/maeder/lib/ghc-6.12.0.20091010/html/haddock.css but a file /local/maeder/share/doc/ghc/html/html/haddock.css and I run: ./Setup configure -O --prefix=/local/maeder ./Setup build ./Setup haddock ./Setup install Cheers Christian P.S.
