1. Install stock Ubuntu 14.04.
2. sudo apt-get install python-dev python-numpy python-biopython

----------------------------------------
Cleaning up...

What version of the product are you using? On what operating system?
Version 0.8.1 on Ubuntu 14.04

Please provide any additional information below.
Seems like the Cython version number has non-digit characters and this causes 
the problem.
