Problem with CLDR when Installing from source

[vgamula]

Hi,

I'm trying to install babel by specific commit, because functionality, which I need, is not released yet (#332 (comment)).
I set -e git+git://github.com/python-babel/babel@903898f97d1010f5bf39b6b6d7e153fc6c2cc15b#egg=Babel in requirements.txt, but, after making messages I got next error:

Traceback (most recent call last):

RuntimeError: The babel data files are not available. This usually happens because you are using a source checkout from Babel and you did not build the data files.  Just make sure to run "python setup.py import_cldr" before installing the library.

So, how can I prepare my cldr data when installing babel by specific commit?

Unfortunately direct git installation is not really supported.

You may want to check out that revision, run python setup.py import_cldr bdist_wheel and use the built wheel as a dependency in your project.

Let me know if you need help!
