On a vanilla install of Ubuntu, the Maven build of the Python client fails because the "pstats" module is missing. Here's a extract from terminal window:

This error is Ubuntu's fault, not ours. The pstats module comes with Python, but the Ubuntu/Debian developers decided that they would rip it out of their default distribution because it's not entirely Free as in speech.

To run our Python build on Ubuntu you have to install the rest of Python, using "sudo apt-get install python-profiler". I've updated the description of this bug; we should provide a better error message when pstats is missing.
