   File "/usr/bin/tahoe", line 6, in <module>
     from pkg_resources import load_entry_point
   File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2707, in

 But since python 2.7 argparse is included in standard library:
 http://www.python.org/dev/peps/pep-0389/, so my system does not have
 separate module for argparse.

Comment (by zooko):

 What's the status of this ticket? Did the fact that I made a new release
 of zfec solve it and now it can be closed?

 Or should we implement one of the suggestions from the comments, such as
 "It will help if tahoe-lafs will declare >= zfec-1.4.23 dependency" (from
 comment:12)?
