It turns out that the only PATH-accessible copy of cabal[.exe] was in
.../ghc-6.4.1/bin, and it appears that cabal by default uses the versions of
ghc and ghc-pkg in the same directory as itself.
Any attempt to install mtl-2 with ghc-6.4.1 is understandably doomed to

The solution was to put a copy of cabal.exe in .../ghc-6.12.3/bin, and then
everything went smoothly.
