Looking into this now.
A commit references this bug:

New revision: 451792
Add missing dependency on p5-IP-Country when the nondefault option
RELAY_COUNTRY is enabled 
While here, carbage collect the UPDATE_AND_COMPILE option from
OPTIONS_DEFUALT, this was most likely missed in r425590
Don't bump portrevision, since this dependency is nut pulled in by default.
