Error installing the glade library for Haskell via cabal

Question

I am using the most recent version of GHC distributed with Ubuntu 11.10 (7.0.3).

When I try to install glade, I get this:

$ cabal install glade

ExitFailure 1

gtk2hs-buildtools and gtk were successfully installed via cabal. But glade does not install. Is this a bug?

Answer 1

I've managed to install the latest glade package via

$ cabal unpack glade
...
$ cd glade-0.12.1
$ runhaskell Setup.hs configure --user
...
$ runhaskell Setup.hs build
...
$ runhaskell Setup.hs build # Note: twice - first build has failed.
...
$ runhaskell Setup.hs install
...

Too bad I have no idea what has caused the error.
