Comment (by simonpj):
I don't know whether this is anything to do with your problem, but I can't
get started:
{{{
bash-3.2$ cabal install
Resolving dependencies...
cabal: dependencies conflict: HTTP-4000.0.4 requires parsec ==2.1.0.1
however
parsec-2.1.0.1 was excluded because rdf4h-0.7 requires parsec >=3 && >=3
bash-3.2$
}}}
Seems that your package dependencies aren't right.
