Ovid, If I understand correctly the issues you raised in the OP, you were attempting to build a Perl 6 binary on an Intel Mac (10.4? 10.5?). Either the instructions weren't clear or it was a genuine problem on that OS.
I suspect that over the past months any such problem has cleared up in the course of other fixes -- but since I don't have an Intel Mac, I can't confirm it myself. Could you give it another try and report if you are still unable to get that binary? Thank you very much. kid51
