Code review comment for lp://staging/~doctormo/python-snippets/lp-merge-request-example

I am getting an error, Martin:

jono@forge:~/source/bzr/python-snippets/launchpadlib$ python merge-request.py
Traceback (most recent call last):
  File "merge-request.py", line 11, in <module>
    os.makedir(CACHE_DIR)
AttributeError: 'module' object has no attribute 'makedir'

Could you take a look and fix?

Also, the snippet does not have the meta-data required, see https://wiki.ubuntu.com/PythonSnippets for details. :-)
