     Type:  update        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.2.1
 Keywords:  haspatch      |       Port:  demeter
--------------------------+-------------------------------
 This patch updates demeter to the latest version, 0.9.19; actually makes
 use of the github portgroup, thereby simplifying the port; and removes the
 need to use the active_variants portgroup.

 It builds, but this may need to be resolved before committing:
