#55891: py-hgwatchman: Portfile missing "version" variable
------------------------+---------------------------
 Reporter:  mndavidoff  |      Owner:
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.4.2
 Keywords:              |       Port:  py-hgwatchman
------------------------+---------------------------
 The Portfile for py-hgwatchman is missing the "version" variable.

 {{{
 $ port info py-hgwatchman
 Error: process_cmd failed: can't read "portinfo(version)": no such element
 in array
 }}}

 This causes `port list` to fail:

 {{{
 $ port list
 ...
 py-hgsvn                       @0.1.9          python/py-hgsvn
 py27-hgsvn                     @0.1.9          python/py-hgsvn
 Error: process_cmd failed: can't read "portinfo(version)": no such element
 in array
 }}}
