In the port's bsd.overlay.mk, there are custom make(1) targets for doing 
these, and they are registered as parts of each phase. Technically 
speaking, just running sccache as a client starts a server if one is not 
already started or cannot be reached, but that operation mode would not 
be suitable in a port build.

The port's patches simply change from using network sockets to Unix 
domain sockets. They are quick and dirty and would need to be 
re-architected for submission upstream, where a big consideration was 
given (and actively used) towards using cloud storage for cached objects.
