ImportError: No module named pyparsing => The pyparsing module is likely 
not installed.

A search of the Internet shows that it should be installable on Ubuntu 
or Debian using [1]:

sudo apt-get install python-pyparsing

While, it is typically installed on Linux distributions with 
easy_install [2] or pip [3] using:

easy_install pyparsing

or

pip install pyparsing
