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
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?

Is `hptool' an executable? If so, then there is no `hptool' in the path.

I have a working installation of the new GHC, but `platform.sh'
requires a tarball, and Cabal.
Thanks for your help.
