There must be a 101 ways to do this. But not having looked at the source for 
your
port, I'm inclined with Ronald.
It wouldn't be unlike getting/using 2 sources from GitHub and combining them 
for
the build. Simply use knob set aside for extra sources. IOW fetch the "extra" 
source
and unpack it in the ${WRKSRC} tree along with your source && include the 
needed
headers from there.

HTH and good luck!
