env for shebang

What steps will reproduce the problem?
1. Use a system where the default python interpreter isn't installed in 
/usr/bin or no python interpreter is installed in /usr/bin.

What is the expected output? What do you see instead?
yubiserve should use the default python interpreter but instead uses the python 
interpreter installed in /usr/bin or fails.

What version of the product are you using? On what operating system?
Version 3.1
Platform independent

Please provide any additional information below.
It would be much nice to use "#!/usr/bin/env python" instead.
