First, I tried to test profiling in  ghc-6.4.1-pre-release,  
and could not -- due to this misfeature with "_p" modules in 
Generally, what I need:  
              fresh GHC with working profiling, with Cabal processing 
              "_p" module suffixes, and such
              (in  runhaskell Setup build, install).

If official  ghc-6.4.1 (with default Cabal version)  has not the 
needed feature, then, the next question is 

  which higher Cabal version supports such `make' for profiling?

After I know the answer to this, I could start searching for possible
_simple instructions_  for the users of GHC and its applications on 
how to upgrade Cabal in their installed  ghc-6.4.1.  Such instructions
that are clear almost to everyone, not only to system hackers.

If all this occurs difficult to arrange, then the profiling occurs 
delayed to future official GHC versions.
