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.

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. Again, installing a separate ghc for the new Platform should resolve this.
