[Haskell-cafe] When I change the cabal file to say preference: base >= 4

[caseyh at istar.ca]

When I change the cabal file to say
preference: base >= 4
I still get, "you are using base 3.0 which is deprecated."
When I change the overall cabal profile, the error message still comes up.
It seems like some other part of the install process is controlling  
the base version, besides the *.cabal and cabal profile file.
