Mac fixes for scons build

[thelusiv]

Alright I've read through the patch a good bit, and understand what you're doing and it looks like it's a good one. Tell you what, rather than make abs1nth apply all that by hand, I'll just give you checkin privileges (the output of svn diff won't usually go through patch, at least for me). Since you seem to understand SCons and building on OS X, I think it would be good to have you on the team.

Please send me a private message or email with your desired username and password, and I'll set it up for you.

Please keep us up to date on any changes you make, so they can be tested on other systems, don't forget to include a log message when you check in too (as descriptive as possible, but doesn't have to include details, those can be discussed here). Also it doesn't hurt to stop by the IRC channel occasionally. Other than that just write good code...and if you don't know how to do something check the SVN book or ask us.
