There are a number of additional dependencies required for getting things installed on OS X. Starting with a blank slate OS X machine, this is the process it takes:

# Install Xcode Command Line Tools

# Install Homebrew
ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"

# A delayed-execution promise.  Promises are only executed once.
#
# @example
#   x = promise { factorial 20 }
#   y = promise { fibonacci 10**6 }
#   a = x + 1     # => factorial 20 + 1 after factorial calculates
#   result = promise { a += y }
#   abort ""      # whew, we never needed to calculate y
