After updating to binutils 2.20.51.20101009-0ubuntu1 in Natty Narwhal,
ghc no longer works:
% sudo dpkg -i

/var/cache/apt/archives/binutils-static_2.20.51.20101009-0ubuntu1_amd64.deb

It works when I downgrade to an older binutils package:

Apparently, --sysroot is disabled in the newer binutils:

I don't know whether this is a problem that should be resolved in GHC or
in binutils.
Let me know if I should provide more information.
Thanks!
