Comment:

 Replying to [comment:7 reneeotten]:
 > agreed that ports shouldn't install stuff in `python.prefix`; not sure
 though if checking for that has a place in the `python` PG or whether I
 should own this ticket.

 No worries, I'll own the ticket then. Just wanted to get some discussion
 going on this.

 In terms of the goal, it seems logical to check for this within the Python
 portgroup. Otherwise, where else would we include such validation
 checks...?
