Have a look at distutils/command/install.py for an example:

         sys_path = map(os.path.normpath, sys.path)
         sys_path = map(os.path.normcase, sys_path)
         install_lib = os.path.normcase(os.path.normpath(self.install_lib))
         if (self.warn_dir and
             not (self.path_file and self.install_path_file) and
             install_lib not in sys_path):
             self.warn(("modules installed to '%s', which is not in " +
                        "Python's module search path (sys.path) -- " +
                        "you'll have to change the search path yourself") %
                       self.install_lib)

Most code we use is of the form:

	sys.path.append('dir')
	sys.path.insert(0, 'dir')
	sys.path = ['/usr/lib/python1.5/site-packages'] + sys.path

How I wish that we had some kind of code base archive for
third party code... e.g. the compile farm would probably be
great for this.
