 Keywords:              |       Port:  QGIS
------------------------+--------------------
 The QGIS port advertises that it installs version "2_18_2" of the
 software:

 {{{
 $ port list QGIS
 QGIS                           @2_18_2         gis/qgis
 }}}

 But as far as I know, it actually installs version "2.18.2" of the
 software. The next time you update the port to a new version, please make
 sure the port advertises the software's correct version number.

 It looks like you're setting version to the correct value, but then
 calling github.setup afterwards, which resets the version to whatever
 value was provided in the github.setup line. The expected usage is that
 you call github.setup first, then override the version later if needed.
