[Haskell-cafe] Link error

Hello,

I'm getting this when trying to build the tests of the 'ssh' package:

--------------------------------------------------------------------
ssh-0.3.2: build (lib + test)

    Process exited with code: ExitFailure 1
--------------------------------------------------------------------

Other people don't get this error. What does it mean, how do I start to debug
and fix it?

Thanks in advance for any clue!
