ImportError on Python 3

Hi, I'm trying to use textile for a project of mine that I want to support Python 3. Importing the textile package triggers an ImportError.

You can reproduce this with tox. Here is my tox.ini file:

[tox]
envlist = py34

[testenv]
deps = nose
       coverage
commands = nosetests

I think the problem is related to relative imports. Here are my results:

matt@eden:~/python-textile$ tox -e py34
GLOB sdist-make: /home/matt/python-textile/setup.py
py34 inst-nodeps: /home/matt/python-textile/.tox/dist/textile-2.1.5.zip
py34 runtests: PYTHONHASHSEED='4057464796'
py34 runtests: commands[0] | nosetests
E
