Digression: Enthought Python Distribution considered awesome
The main reason I made this program is because, alongside the Apple-supplied python and the vanilla pythons from python.org, I use a python distribution dedicated to scientific work.
Anyone who ever lost an afternoon trying to install numpy and scipy from sources should make herself a favor and try this instead. It's not merely a collection of compiled packages. It's a damn platform.
You should be thankful for this. I know I am.
Alright, alright. So what's new?
Well, the program described in my latest entry suffered from at least one major flaw: it did not detect the 64bits builds of EPD.
The reason for this is that they are installed under yet another directory (namely, /Library/Frameworks/EPD64.framework.)
That's it. It's still a really simple program, but serves its purpose. Grab it on github.
What's next?
I realize that this is a really simple and, perhaps, clumsy way to switch between multiple python runtimes.
Ideally, this should be built into the OS. For every interpreter or compiler you might want concurrent versions of. Something along the lines of the 'alternatives' system you can find in some linux distros.
But for now, that's all there is.
Priorities.
