[Haskell-cafe] Fwd: [Gtk2hs-users] Installation problem with cairo.

[Magicloud Magiclouds]

Hi, I cannot subscribe to libraries maillist. So I forward this here.
I cannot install gtk2hs-cairo by cabal using cairo 1.9.6 compiled
myself. Cabal always said that the cairo library/devel files were
missing.

Hi again,

it's very difficult for me to say what is happening. Could you ask on
the cabal mailing list to see if anybody there has an idea.

Cheers,
Axel
