true, but from what i have been able to sniff out on my own, ports
configuration data are stored in /usr/local/include, not anywhere in the ports
tree, so that if png has been installed already & you do a "make showconfig"
in /usr/ports/graphics/png, the data are read from files in /usr/local/include,
& if you run "make config" in /usr/ports/graphics/png, the files affected by
any change are in /usr/local/include, not anywhere in the ports tree.

this has been a learning experience for me & prolly will continue to be as
others here correct me.
