Thanks for all considerations.  I have now successfully loaded my custom
resource file.  After doing some re-reading at icu site the key  elements
were:
 1.  Set environment variable ICU_DATA to locate the file
 2.  Initialize Resource bundle as ... rb = ResourceBundle('bundle_name',
Locale('ex_MX'))

Thanks again for anyone's considerations.
