I got the prompt right back, no error message.

I haven’t tried your other suggestion yet.

. . . .

Your error message suggests the old version (which may be the only one  
compatible with Balint’s gr-baz stuff; not sure).

So as a preliminary test, could I have you run a simple test; open the  
python interpreter interactively [just type python], and try  
import op25  
at the python \>\>\> prompt.  
–please report the result – do you get an error on this?
