Which Cabal version will be in official ghc-6.4.1 by default?

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

If it is 1.0, then ghc-6.4.1 will fail with `make' for profiling. So, the user needs to install another Cabal version and to link it to GHC, and this occurs difficult. This is likely to complicate the usage of GHC

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.

First, I tried to test profiling in ghc-6.4.1-pre-release, and could not -- due to this misfeature with "_p" modules in Cabal-1.0. 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.
