I will try a more recent cabal-install this evening.
Thanks for the speedy response!
[Time passes - second response:]
I have tried cabal-install build from the latest revision (4aabb4f4b1)
with the same result. From a clean checkout of my source:
$ ~/cabal/cabal-install/.cabal-sandbox/bin/cabal configure
--disable-tests --enable-coverage --disable-profiling
$ ~/cabal/cabal-install/.cabal-sandbox/bin/cabal build -v
