[Haskell-beginners] can't install hackage package

[Emmanuel Touzery]

i have now installed pcre-light separately, it still doesn't work.
i think the problem is that it claims that ghc is an unknown package. that
was working on other computers. maybe there's something note quite right
about the way it's all configured on the (just released) fedora18 haskell
platform setup?
