Hi, Paul--

There is little point to crossposting between -questions and -hackers; 
dropping the latter.  Actually, <ports at> is probably the most 
appropriate place...

Well-behaved ports respect CFLAGS, meaning that you can define that variable 
in /etc/make.conf (or on the command line when you invoke make), and the port 
should use that value when building the software.

If you tell us which port is broken, someone will fix it.  For example, one of 
the ports I maintain the author explicitly sets -O2, but the port Makefile 
patches that via:

         ${REINPLACE_CMD} -e 's/-O2//' ${WRKSRC}/Makefile
