Please post the output of:

This copy should not exist.  Any idea where it came from, and what is
its contents?

If your /usr/bin/cc reports being clang 6.0.0, then the latter one is

My guess would be that something (/etc/make.conf, for instance) is
messing with your CFLAGS, causing the internal headers to not be found.
