Things related to PHP and Ruby.

MAMP does not get updated quickly enough. Full stop. From here on out
I'm switching to [PHP for OS X](http://php-osx.liip.ch/). It's a bit better
but still a pain to get working easily.

As per [this comment](https://github.com/liip/php-osx/issues/75#issuecomment-25445956):

    export DYLD_LIBRARY_PATH=/usr/local/php5/lib
    curl -s http://php-osx.liip.ch/install.sh | bash -s 5.5
    unset DYLD_LIBRARY_PATH

This seemed to work-ish. Note to self: do not use the pipe-thingy.
