The line desc=TURN and STUN server should be desc="TURN and STUN server" It gives an error otherwise.
^Triage: Re-assign to net/turnserver maintainer: net/coturn was removed April 9 [1], as it duplicated net/turnserver. [1] http://cgit.freebsd.org/ports/commit/?id=b91f6147e4171425696f74c1f26de83a6ea3593a
Doesn't apply to turnserver. As coturn is gone, this problem will be fixed by switching to turnserver.
