Duncan, thanks for replying.  Trying to use ghc --make Setup.hs failed
with a bunch of linker errors, (although ghc-pkg reported that only
Cabal-1.2.3.0 was installed), so somehow my Cabal libs must have
gotten messed up.  Anyway, rebuilding and reinstalling ghc fixed it.
I don't know why cabal didn't fail on the other packages, maybe I
forgot to clean them before I re-ran configure.  I also don't know how
the library got messed up; maybe I modified some other package that
cabal depends on.

Thanks,
John
