Exception: IndexError: list index out of range when installing thunder on Ubuntu 14.04

After running sudo sudo pip install thunder-python on Ubuntu 14.04 with python 2.7.6 I get the error

Cleaning up...
  Removing temporary dir /tmp/pip_build_root...
Exception:

It appears to be some clean up processing that errors but when I try to import thunder
pip.log file is attached
pip_log.txt

in python

What version of pip are you using?

[mobcdi]

pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)

[mheppner]

Latest version of pip is 8.1.2. Try upgrading with sudo pip install -U pip.

Running sudo pip install -U pip followed by sudo -H pip install thunder-python worked. I was able to

import thunder
thunder.__version__
'1.1.0'
