Homebrew works, after you run 'brew update' (in case you haven't already, I'm guessing). Initially got erros 'Cannot defer diagnostic messages' for pr, but updated brew seems to be working well.
Installing MacPorts is easy, however, be aware that some ports do not compile yet. Some of them have bugs filed against them, but given the NDA, MacPort developers could not fix them until Lion was out.
Waiting is always the hardest part :P.
