</div></div>Not sure as I'm the one on the team who doesn't own Mac hardware. That said,<br>
as I recall some of the tips by Simon it is generally best to start from<br>
source on OS X. So maybe you "just" need xcode etc on a 64-bit Mac. Others<br>
may fill in with more pertinent hints and recommendations.<br>
