#59910: wireshark3: python variants only add a dependency
------------------------+------------------------
 Reporter:  ryandesign  |      Owner:  ghosthound
     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.2
 Keywords:              |       Port:  wireshark3
------------------------+------------------------
 The wireshark3 port has several python variants described as letting the
 user choose which will be used for building, but the variants do nothing
 other than add a dependency on a python port. Each variant also needs to
 inform the build system to use that specific python.
