No languages available when installing Trac as wheel

[Ryan J Ollos]

When Trac is install as a wheel, the default when using pip, the languages aren't available.

$pip install trac
Collecting trac

However, if Trac is installed using the --no-binary option, languages are available.

$pip install --no-binary=trac trac

That is not a Trac issue. I think you've installed Trac without Babel and created *.whl package is reused.

$ /dev/shm/t12391/bin/pip install --verbose Trac

Reconsidering, we could upload *.whl package with language files to PyPI in order to install without local-building.

It looks like you are correct. Languages are available if installing wheel using --no-cache-dir option.

I like the idea of creating a wheel at the next release. I guess we should create a ​pure python wheel since we don't yet support Python 3.
