Zope is unable to add the external method because there is a python error 
('No module named nb_parse') which stops zope from loading the external 
method.  Two possible fixes:

1) set your path to include the directory where nb_parse.py lives.
eg.
    import sys
    sys.path.append('/apps/zope/lib/python/mypythonroutines')

Also, make sure the group/ownership of the directory and python routine 
files allow zope to access them.

2) try 'hardcoding' the nb_parse routine within nb_fetch.py.   If this 
works, then your problem is definitely related to pythonpath not being set 
up (or zope can't access the directories/files in the path).
