BTW: On older FreeBSD, you can't use a ports C++ to compile
C++ code, since bsd.prog.mk and bsd.lib.mk reset the include
path and will get you the older headers all the time, if
DESTDIR is set, which it will be.

If you are using a ports C++, then to see if you have this
problem, type the following:

	cd /usr/share/mk
	grep include/g++ *

If you see:

	bsd.lib.mk:CXXINCLUDES+= -I${DESTDIR}/usr/include/g++
	bsd.prog.mk:CXXINCLUDES+= -I${DESTDIR}/usr/include/g++

Then you have the problem.  This is fixed in 5.x; I'm not sure
if it has been MFC'ed into more recent -stable, or not (i.e.
it may not be a problem on 4.8; the above is from a 4.6 system).
