I've had this problem as well. I think the issue is that 'cabal' now
expects '--disable-profiling', but if you have a custom Setup.hs, it
can be compiled with an older version of the Cabal library, and then
it expects '--disable-executable-profiling' again. What is the output
of 'ghc-pkg list Cabal'?

I have 3 versions of Cabal as reported by "ghc-pkg list Cabal".

Cabal-1.16.0 in the global package db, Cabal-1.18.1 and Cabal-1.20.0.0 in the user db.

Do you think I should be hiding the old ones?
