coherence breakage with twisted-16.5.0

[0-wiz-0]

When building with python-2.7 and twisted 16.5.0, the build of 0.6.6.2 fails with:

Twisted >= 2.5 and Twisted.Web >= 2.5 are required. Please install them.
Traceback (most recent call last):

This was a packaging problem with twisted in pkgsrc (missing dependency), which is now fixed. Nothing to do here, sorry for the wrong bug report.
