You can't have two versions of the Platform installed into the same ghc; ghc will become extremely confused. This is essentially a ghc shortcoming that the Platform can't work around.
However, the README says: The machine doing the build needs to have a working Haskell setup: Usually, GHC (7.4 or later), Cabal (1.16 or later), and haddock and HsColour must be on the $PATH. This is what I am trying to do: I have a working installation of the old GHC plus the old Platform, and I am using it to build the new Platform. Otherwise, where am I supposed to get Cabal? AFAIK, Cabal comes with the Platform. Am I missing anything?
The hptool issue is likely that you have an older version installed than the new Platform requires, and the newer one is not compatible with the older Platform.
Is `hptool' an executable? If so, then there is no `hptool' in the path.
Again, installing a separate ghc for the new Platform should resolve this.
I have a working installation of the new GHC, but `platform.sh' requires a tarball, and Cabal. Thanks for your help.
