botocore uses cElementTree and does not declare it as requirement

[bsiegert]

I am a developer on pkgsrc, and we got a bug report (http://gnats.netbsd.org/54094) that is ultimately due to botocore.

$  aws help
Traceback (most recent call last):

[now works]

In botocore/compat.py, line 172, there is an import for cElementTree but the requirements (setup.py and others) do not mention this dependency/

It is not listed in the requirements because it is part of the Python Standard Library. There is no need for us to declare it as a dependency as it is automatically included in all versions of Python we support. Let us know if you have anymore questions.

Whoops, I did not realize that cElementTree being a separate package is pkgsrc-specific. Sorry for the noise and thanks.
