I suggest a different tactic. Try replacing the line: _xmlplus.__path__.extend(__path__) with _xmlplus.__path__[0:0] = __path__ At the moment, the replacement works as follows: 1. Both the stdlib and PyXML package dirs are on the package path 2. In the case of name clashes, prefer the PyXML version By changing it to put the stdlib path first, you would instead set up the following: 1. Both the stdlib and PyXML package dirs are on the package path 2. In the case of name clashes, prefer the stdlib version (This should work, because PyXML doesn't import anything implicitly in __init__.py) Since Toshio reports that the current behaviour is genuinely causing problems, you could probably make a case for this approach as an upstream bugfix, especially if you implement it in Fedora first with no apparent ill-effects for affected applications.
