We've had a great process for setting up new developer Macs for a long time, but we've been slow to share it. Today we corrected that oversight by releasing The P'unk Avenue Loadout, an open source setup process and script for new Macs.
The Loadout is designed not only to install the missing bits and pieces necessary to properly test modern web apps on your own Mac, but also to do that in a maintainable, future-proof way, thanks to MacPorts and its ability to build software packages from source code in an automated and easily updated fashion.
We consider it an important part of our commitment to open source. We believe a rising tide lifts all boats. More than that: we believe it's boring to sit out in the middle of the ocean all by yourself. And with any luck, someone will send us a pull request to upgrade our schooner to a dreadnought.
