include_path

Is there a way of modifying the include_path within a script, I want to add to it, not completely change it. The sort of thing that I want to do is equivalent to the following bit of shell code: PATH="$HOME/bin:$PATH" ie add a user specific part to the path - so that a production/test 'require' gets the production/test version of a file. Please CC me on any reply since I don't subscribe to this list.
