i placed the catwalk.py in the directory containing model.py and i did a little modification that replaced the line " from turbogears.catwalk import CatWalk " to " from catwalk import CatWalk " to avoid a traceback that can't find modules.
when i finished all the works, i can't run "python devtesting-start.py". and i got a error box says "This application has failed to start because sqlite3.dll was not found. Re-installing the application may fix this problem." again.
