That's all a good sign...

not sure if following is significant:

Something is amiss in how things ended up on your machine. I've just double
checked the contents of the Mac distro and /opt doesn't appear in any of
the package registrations. Furthermore, unless you built Cabal-, it
shouldn't be in your package db. My rough guess is that you've got a 7.8.3
compatible package db left over from a prior install somewhere. Can you
e-mail me directly the output of:

which cabal
cabal --version
which ghc
ghc --version

which ghc-pkg
ghc-pkg --version

ghc-pkg list

ghc-pkg dump
