FYI: I do not understand what you mean by 'overlapping time frames'

Ok, there are 3 ports involved:

1) authoritative dns:		dns/knot3
2) library part of dns/knot3:	dns/knot3-lib
3) recursive dns:		dns/knot-resolver

2) is needed by 3), 
thus compiling 3) pulls all libraries and includes from 1),
and stores them in the very same locations as 1) will.

Thats, if I am not mistaken, the reason for pkg complaining 'pkg-static: knot3-lib-3.3.3_1 conflicts with knot3-3.3.3_1 (installs files into the same place).'

Thus, IMHO, both ports dns/knot3 and dns/knot-resolver cannot be installed simultaneously. One could install them in different jails, but that is not an option for me.

Possible solutions:

1) dns/knot3-lib should store its libraries and includes into a different location as dns/knot3 does
2) discard dns/knot3-lib and make dns/knot3 and dns/knot-resolver mutually dependent
3) …?

I am not an expert in ports internals, thus: what would the best way to solve this issue?
