There are a few funky things going on here. 

First, running openev should use the internal copy of python,
but from the error message it is clear that the python from 
/usr/lib is being used instead. 

Second, I see that in *my* python 2.2, the low level strip method
invoked in string.py has no argument, but it does in 2.3.  I would
guess then that your local (/usr/lib) python scripts like string.py
are getting used, but with the python C binary distributed with
FWTools and they are incompatible. 

How did you invoke openev?  Did you run the script in
bin_safe or run the one in bin directly?  You *should* be able
to run the one in bin if you have setup the environment, but if
you run the one in bin_safe it will setup the environment properly
for sure.

Let me know as if there are issues with the way I force use of
my distributed python I would like to fix it.
