With GHC version 6.8.2, ghci gives the error:

Yes, this is a known bug. Xen doesn't respect the MAP_32BIT flag to
mmap(), which GHC on x86_64 relies on.

GHC version 6.10.1 gives a similar error:

These same 2 results happen on 2 different distros that I've tried.
With both GHC versions, compiling haskell programs sometimes works,
but sometimes hangs during the linking stage.
Compiling and running executables should work fine, only GHCi is affected
by the above bug. Could you try -v when linking and see what stage is hanging?
Cheers,
Simon
