Error when building Panda3D on Mac

Hi. I'm trying to compile Nirai's Panda3D on Mac OS X Yosemite, but I can't due to some error with OpenSSL. I don't think it is installed, so if this is causing the problem, can someone point me in the right direction so I can download it? (I'd assume it's simple, but I know nothing about Macs. Got this one recently) Here's my build log:

Any and all help is appreciated, thanks!
