Installing TeX from source is weird and gross, requires a lot of patches,
|
||||
and only builds 32-bit (and thus can't use Homebrew deps on Snow Leopard.)

We recommend using a MacTeX distribution:

npm can be installed thusly by following the instructions at

http://npmjs.org/

curl http://npmjs.org/install.sh | sudo sh

When working with a Homebrew-built Python, distribute is preferred
|

over setuptools, and can be used as the prerequisite for pip.

Install distribute using:

brew install distribute
