Although I don't use the latest version of FreeBSD, I don't think
package system of FreeBSD is so officious to set the environmental
variants for the compilers, so I sympathize with Miles.

However, pkg-config installed by the binary package scans following
directories automatically.

Yet I've not checked if the binary package of gcc (not the default
/usr/bin/cc, installed to /usr/local/bin) will search /usr/local
trees by default.
