You can add module (and submodules) with sys module.

For example in mediagoblin/tests/tools.py before line beginning by 'from mediagoblin ...'

import sys

# Full path of mediagoblin
sys.append('/spare/usr/ports/www/py-mediagoblin/work/mediagoblin-0.8.1/mediagoblin')

You need also add subdirectories (that's why it's not easy to debug, because some directories is not necessarily Python's module, no __init__.py file).

Another way is to use os.walk() function:

import os
import sys

# mediagoblin full path
goblin_path = '/spare/usr/ports/www/py-mediagoblin/work/mediagoblin-0.8.1/mediagoblin'

for root, dirs, files in os.walk(goblin_path):
  for name in dirs:
    sys.append(os.path.join(root, name))
