That is not correct. If you run Modeller with the mod9.15 script, that uses a built-in copy of Python 2.3, so it would only work if you also had the Python 2.3 modules available. But we generally don't recommend that these days (Python 2.3 is really really old). Run your scripts with the system "python" instead like any other Python script. If you installed the RPM (it looks from your traceback as if you have) then you are already good to go. If you installed the .tar.gz, then it will have told you how to set PYTHONHOME and LD_LIBRARY_PATH to make this work.

Every version of Python has the socket module, including Python 2.7.
