I was tying to figure out how the anaconda installer works. I was executing the isys.py script under the isys subdirectory using this command. python isys.py and i get this error. File "isys.py", line 19, in ? import isys ImportError: No module named _isys when i look at the source code there is a line that says import _isys when i search for _isys there is no file or directory with that name. are the modules in _isys system generated? how do i fix this so that i can run "python isys.py" with no errors. thanks. erwin
