     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.3.4
 Keywords:          |       Port:  py-pyml
--------------------+----------------------
 This surfaced with r143293 which however is not the cause the issue. The
 port was not really maintained since r92119, so very probably it's just
 bit-rotten:
