py-twisted 17.5.0: missing python package dependency 'hyperlink'

[kpreid (Kevin Reid)]

Since upgrading to py27-twisted 17.5.0_0, the code import twisted.web.template, for example, will fail because Twisted 17.5.0 introduced a dependency on the Python package hyperlink which is not installed by MacPorts: ​https://github.com/twisted/twisted/commit/e2e0c715072ea129431031e9ed2428262f7e4a42

Fixing this will require creating a port for hyperlink, but I assume this will be straightforward.

>>> import twisted.web.template
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/twisted/web/template.py", line 571, in <module>
