overview.overviewconfig.project_path_not_found

I pulled the code off launchpad and installed it successfully. I can't however run the program itself and get this error:

Traceback (most recent call last):
  File "/usr/local/bin/overview", line 267, in <module>
    window = OverviewWindow()
  File "/usr/local/bin/overview", line 159, in __new__
    builder = get_builder('OverviewWindow')
  File "/usr/local/lib/python2.6/dist-packages/overview/helpers.py", line 29, in get_builder
    ui_filename = get_data_file('ui', '%s.ui' % (builder_file_name,))
  File "/usr/local/lib/python2.6/dist-packages/overview/overviewconfig.py", line 39, in get_data_file
    return os.path.join(get_data_path(), *path_segments)
  File "/usr/local/lib/python2.6/dist-packages/overview/overviewconfig.py", line 56, in get_data_path
    raise project_path_not_found
overview.overviewconfig.project_path_not_found

I'm running ubuntu maverick.

Thanks!
