You did not get your script but the object's method of the same name.

You can use my "DocFinder" product

  <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

to find out what methods an object has and avoid their names.

Maybe, a better approach is to use consistent prefixes or suffixes
for your own utility functions (such as "myGetRelativePath") to
make name clashes unlikely without initial investigation.
