OS X Support

What's the current status of OS X support? I understand that 4.3 will be the first release to "officially" support OS X but how much of the work is complete in current CVS? I grabbed the latest yesterday and compiled it -- still had my issues creating files and directories (Where I would get permission denied errors even though the perms were 777 and the entire directory was owned by the webserver user/group).. I ran into this problem using Smarty and evidently a lot of people have had it with 4.2.. I also couldn¹t get mcrypt to work in 4.3-dev -- "unable to open encryption module" for everything I tried (this worked fine in 4.2). I have libmcrypt 2.5.0 installed, which appears to be the latest available... I would roll back to 4.1 but I can't get it to compile on this box and the only OSX build I've found doesn't have working mcrypt support and I kind of have to have it :-) Thanks to all!!! -Mitch
