The version available on Mavericks is 2.7.5.

we should install virtualenv like we do with the linux workers, but talk to the great @dstufft about how we might install prebuilt python binaries on demand? :)

[dstufft]

I'm not aware of anything like that existing currently. I had some sketches for something like that but I don't have near the time to do that.

[joshk]

maybe we can talk more about your ideas, and what you think the time commitment would be to build it, and then we can see how we can make it happen?

[dstufft]

I'm happy to discuss them, but it's unlikely there'll will be much that'll give me enough time to build it. I'm running on fumes as it is.

[joshk]

oh, no no no, i don't expect you to build it, but thinking maybe we can help fund it or something?

[dstufft]

Ah. Well I'm happy to advise or whatever :) It's not a very complicated thing I don't think. Fundamentally you just need a way to map an environment and maybe compile options to an identifier that you can use to download and unpack.
