Yes, perhaps the README should be tweaked to explain non-root
installations.  Actually, all you have to do is "make setup" and then
install normally like any other package, except for the business of
hiding the older version that's explained in the README.

You can use "runghc" or "runhugs" you may or may not have "runhaskell"
depending on your platform.

It'll be 1.0 with some bug fixes (Simon: can you please make the
version number '1.0.1'?)

Yep.  Profiling support won't be there, but some of the problems you
faced in building a separate Cabal will hopefully be fixed in the new
version of GHC.
