Finally set up everything correctly and got Patrick's original community running on 128.213.11.151 for testing.

** Initial Setup
In step 6) Install ezPyCrypto library manually (Pycrypto 2.3)
sub-step 1)
The link downloads Pycrypto-2.3, NOT ezPyCrypto.
You can download ezPyCrypto here:
                                   http://freenet.mcnabhosting.com/ezPyCrypto/
                   Then follow sub-step 2)-4). 
                   I downloaded and installed both Pycrypto-2.3 and ezPyCrypto.
