Comment (by mojca@…):

 I'm waiting for maintainer to either accept or decline the patch for `py-
 robotframework-ride`, but it has a separate ticket open. The ports for
 `grass` and `py-pyface` were fixed, `pyphant` is semi-broken and not worth
 patching now, but will hopefully fully support wxWidgets 3.0 when it
 "raises from the dead". `spe` and `py-dsv` don't need anything.

 Thus I'm closing the ticket.
