Comment 14 for bug 782414

there are still some issues with this update when twisted meta package is not installed as the requires.txt still lists it as a dependency, also a runtime dependency on setuptools is required as the zope egg requires it but does not depend on it.

without the twisted meta package:
# python -c 'import pkg_resources; print pkg_resources.require("foolscap[secure_connections]")'
Traceback (most recent call last):
...
pkg_resources.DistributionNotFound: twisted>=2.4.0

with twisted and without setuptools:
# python -c 'import pkg_resources; print pkg_resources.require("foolscap[secure_connections]")'
Traceback (most recent call last):
...
pkg_resources.DistributionNotFound: distribute

these issues are not really important as tahoe, the only user of this feature, depends on both missing packages.
