I checked this file and it's there and readable. I see this in setup.py in data_files():
Code:
files.append(('.', [(opj('bin', 'import_xml.rng'))]))
...
files.append((openerp_site_packages, [('bin/import_xml.rng')]))

But it does not find the file for some reason.

This occurs on a RedHat Linux system.

When I print out 'files' list it shows:
