The only requirement to import a module (and its content) from
an External Method is that it (or a package chain containing it)
is reachable via "sys.path".

You can see the "sys.path" used by Zope in
"Control_Panel --> Debug information".

"sys.path" is setup from the "PYTHONPATH" environment variable.
Zope extends it by its "lib/python" and (maybe) "$INSTANCE_HOME/lib/python".
Python extends it by references to its runtime library
and mechanisms documented in its "site.py" module.


Import in internal Python scripts requires security declarations.
This is documented in the Zope Developper guide and
(partially) the "README" file in "Products/PythonScripts".

When the security declarations are not there, you get
an "Unauthorized" exception.
