 Replying to [comment:5 ryandesign]:

 increasing the revision is mandatory.

 Ah yes, you are right of course. I misinterpreted the condition.

 > Installing the bindings in a variant is not ideal because ports cannot
 depend on variants of other ports; see #126. Instead, it would be
 preferable to make the bindings available via a subport or separate port.

 Where can I find more information on how to do subports in Portfiles? I
 only found [https://trac.macports.org/ticket/36957 this ticket], which is
 still open... Perhaps a small port with subports that can be an example?
