direwolf @1.6_1 -- fails to Build - libgps API version might be incompatible

[RobK88]

I am unable to build direwolf on High Sierra (and on Lion). Both fail with "libgps API version might be incompatible".

See below and attache main.log

bash-3.2$ sudo port clean direwolf
--->  Cleaning direwolf
bash-3.2$ 
bash-3.2$ sudo port -v install direwolf

,.. etc etc
