Just some small notes about how to run FLOW3 on a mac.
Installing PHP 5.3.0beta1
FLOW3 requires PHP 5.3 in the current version. Macport is a greate tool (like apt*) for compiling and upgrading software. So the first thing you need to do is download: www.macports.org.
After downloading and installing macport you can use the port commands to download and install new software with its dependencies. For PHP 5.3 you can use this commands:
sudo ./port selfupdate -f
sudo ./port search php5
sudo ./port variants php5-devel
sudo ./port install php5-devel +apache2 +macosx +mysql5 +sqlite
More details on http://guide.macports.org/.
You can get the current version from SVN: svn co https://svn.typo3.org/FLOW3/Distribution/trunk/.
Since php 5.3 is released its now available with the port "php5":
( sudo ./port installed )
sudo ./port uninstall php5-devel
sudo ./port install php5 +apache2 +macosx +mysql5 +sqlite
To run flow3 / TYPO3v5 you need to have a valid pear installation:
wget pear.php.net/go-pear.phar && php go-pear.phar
