Comment (by ryandesign@…):

 The github portgroup should be used. If possible, fetch from the github-
 generated tarball instead of directly from the git repository. See
 comments in the github portgroup for instructions.

 Why are any of the variants needed? All they seem to do is install
 additional files, which the user can use if desired. Why not just always
 install these files?
