[erlang-questions] problems building r11b-3

[P]

          Hej Ulf  !

   It's not that the different builds are keept "on top" of each others
(and built in some specific order)?

   I've remember I had some strange results from time to time resolved by 
viping out the previously builds entirely and then rebuilding the latest
again.

                        Regards
                        Per Einar
