Comment (by ryandesign):

 Has duplicate #57082.

 Replying to [comment:7 pmetzger]:
 > Perhaps we could maintain both 6 and 7 as distinct ports

 Yes we could do that.

 > and conflict them?

 No, I would not want to do that. I would want them to install to distinct
 locations and not conflict, so that ports that require version 6 can
 depend on that and ports that are ok with version 7 can depend on that.
