Started using Doctrine recently. Was going smoothly until their online documentation suddenly disappeared. I’m sure it will return, but in the meantime I was up a creek. Found that the orm documentation is available on github, but you have to build it first. And it has a PILE of dependencies. First, don’t use the [...]

It appears Autotools is no longer bundled with Xcode as of 4.3. I discovered this while trying to install a few php extensions via MacPorts. They all kept failing with the log reporting the following error from phpize: Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable.

I knew what I wanted was probably [...]
