    Module operator should come from file operator.so, presumably in /usr/local/lib/lib-dynload in your case since that seems to be where you’ve installed things. So what .so files are in that directory?

    Assuming operator.so is indeed missing (i.e., assuming it’s not some trivial case of wrong permissions on some directory or file) the best way to “get it back” is no doubt, as a comment already suggested, to reinstall Python 2.5 (assuming you need that release e.g. to work with app engine) from either an official Python package at python.org, or an official CentOS 5.3 one (if one exists — I believe CentOS 5.3 uses Python 2.4 as the official /usr/bin/python but there may be RPMs to place 2.5 somewhere else).
