----------------------------------------

Building PhantomJS from source takes a very long time, anywhere from 30 minutes
to several hours (depending on the machine configuration). It is recommended to
use the premade binary packages on supported operating systems.

For details, please go the the web site: http://phantomjs.org/download.html.
