Not really, at least with python, as per /usr/ports.UPDATING. I understand all 
this. My question was/is all this really necessary. The answer seems be be not 
with python. I pondered about Qt as that is a pretty basic component in a GUI 
environment. In any case I think having to essentially rebuild my workstation to 
install a utility to store passwords is not something that should be defended. I 
can slide to 11.4 when the time comes.

I appreciate all the comments and information. I have information as to going 
forward with my obsession of using FreeBSD as a workstation.
