Attempt to fix node-gyp error: No package 'cairo' found

install_cairo.sh

# Fix node-gyp error: "No package 'cairo' found"
#
# Installs Pixman, Cairo and (if absent) pkg-config
# N.B. You may want to first cd into a preferred source directory (e.g. ~/src).
#
# Desc:
# This script attempts to fix a node-gyp error, "No package 'cairo' found",
# (that in my case appeared) when trying to npm install --save metalsmith-stylus.
# Basically, installing Cairo + Pixman (http://www.cairographics.org/) did the
# trick for me. (Might come in handy in similar situations with the same error.)
#
# You may want to check for newer/specific versions of specified libs first.
