Dane,
I looked within the System Environmental Variables and it already had
C:\mapnik_0_6_1\site-packages within the pythonpath. So I added
C:\mapnik_0_6_1\site-packages\mapnik\ogcserver\ to the pythonpath and
I still get the same error listed within the previous email.
I switched the user that apache is running under to the default of
Local System with the same error.
Finally I appended to the sys.path
'C:/mapnik_0_6_1/site-packages/mapnik/ogcserver/' for the python
script (listed below) and I am still getting the "ImportError: No
module named mapnik.ogcserver.wsgi" error.
#!c:\Python25\python.exe
import sys
sys.path.append('C:/mapnik_0_6_1/example_code/wms/')
import os
WORKING_DIR =
os.path.dirname(os.path.abspath('C:/mapnik_0_6_1/site-packages/mapnik/ogcserver/'))
sys.path.append(WORKING_DIR)
from mapnik.ogcserver.wsgi import WSGIApp
application = WSGIApp('C:/mapnik_0_6_1/example_code/wms/ogcserver_4326.conf')
