# This python script creates Finder aliases for all the
# dynamically-loaded modules that "live in" in a single
# shared library.
# It needs a fully functional non-dynamic python to work
# but you can run it in a shared python as long as you can point
# it to toolboxmodules.slb

Try the following:
1. Remove any old "Python Preferences" files from the system folder.
2. Remove any old "PythonCore" or "PythonCoreCFM68K" files from the system folder.
3. Make sure this script, your interpreter and your PythonCore are all located in the
   same folder.
4. Run this script again, by dropping it on your interpreter.

If this fails try removing starting afresh from the distribution archive.
