[Distutils] package data not installed from python .egg file

[Roban Hultman Kramer]

I'm trying to include some data files in a python package using the
setuptools package_data option. I'm then accessing the files with
pkg_resources. This works perfectly when the python .egg file is
installed as-is (i.e. still zipped). But when the egg file is unzipped
during installation, the data files are not installed.

In other words, if I run:

  python setup.py bdist_egg
  cd dist
  sudo easy_install -z EnrichPy-0.1.001-py2.6.egg

then the egg file is installed (with the data safely zipped inside)
and everything works.

On the other hand, if I run

  sudo easy_install -Z EnrichPy-0.1.001-py2.6.egg

then the data files are not installed. I have a directory called
EnrichPy-0.1.001-py2.6.egg/enrichpy/ under dist-packages, but it
contains only my source files, not my data files.

Can anyone suggest what I need to do to get the package_data files to
be installed when easy_install unzips the egg file?

Notes:

The package is available at http://github.com/roban/EnrichPy

I can test it by running:

  import enrichpy.yields
  enrichpy.yields.Data_vdHG().data

If that exits without errors, then pkg_resources is finding the installed data.
