There's something about this that I don't understand. How is deleting the name from sys.modules different from reloading it, which as you already explained [1] is not going to work? I can think of two approaches that will work for python >= 2.3: 1. Import setuptools to get a copy of its __version__ attribute, import pkg_resources to use its parse_version() function, then del them from sys.modules. (As above, I don't understand how deleting them from sys.modules and then importing them is different from reloading them.) 2. Use os.system() instead of subprocess() to get the version of the installed setuptools, include a copy of the parse_version() function from pkg_resources. The second approach seems clean and robust to me, and I would be happy to submit a patch that does it if you are interested in seeing one.
