[Jython-dev] Jython calling curses module...

[Matthew W. <sp...@wr...>]

I was playing with Jython a bit and found this problem (or at least, 
something I'm doing wrong):

I'm trying to compile a python script that imports the curses module, 
and I get an error 'ImportError: no module named _curses' error.  I 
copied the modules from my python-2.0 directory to jython/Lib and got 
further, but still the error boils down to '_curses' not being found.  
Any ideas?

Verbose errors:
