How do I install idlefork under Linux (RedHat 7.1 iwith Python 1.5.2)? If I simply copy the files into a random directory I get an import failure as idle imports PyShell which imports warnings which does not exist. warnings does exist in the Python 2.1 Windows version in Python21/Lib/warnings.py - I don't find anything comparable under Python 1.5.2 on Linux.
