We've had two other reports of this on BSD-based systems, and I've had
it myself on OpenBSD. The problem appears to be Cabal not propagating
ld flags.  And it seems to be fixed in the newest Cabal.

Brad, could you try updating Cabal to the most recent release, and then
try again?

If that does indeed fix it, I'll start an FAQ web page for this info.
