Hi; does anyone have duplicity working on OS2008? I installed it apparently successfully, but when I try to run it from the command line, I get

ImportError: No module named getpass

Since getpass is a python system module, it looks like my python installation is hosed.. but other apps, using python from the launcher, seem to run OK. So I guess it is possibly a path problem. If so, does anyone know what magic I need to get python to find the system classes? Or do I need to install the python development system for the system libraries to be available (I tried to install it, but get an uninformative error from application manager - just tells me it failed to install, with no diagnostics)

TIA
Bob
