     I had read that and hadn't seen how that would work, but after seeing
your reply, I tried adding the three lines to /etc/make.conf and got errors,
like I had expected:

make: "/etc/make.conf" line 18: Missing dependency operator
make: RE substitution error: repetition-operator operand invalid
make: Unclosed substitution for CXX (, missing)
make: "/etc/make.conf" line 20: Undefined variable "${CXX:C,^c++,/usr/local/libexec/ccache/world/c++,1}"
make: Fatal errors encountered -- cannot continue
make: stopped in /usr/src

     So my question remains.  Please respond if you have something that
you have tried and know works.
     Thanks in advance.
