Hi Antione,

I used the tarball ghc- and followed the 
directions in the README file:

     $ perl boot
     $ ./configure
     $ make

(The "perl boot" command wasn't necessary, since I was building from a 
tarball instead
of a darcs pull.  However, it didn't cause any problems.)

I haven't run a testsuite on the build yet.  Perhaps someone from 
haskell HQ can
tell me which version of the tests I should run on 7.0.1-rc2?

Best Wishes,
