Nothing in /usr/local is going to be changed until "make install"
(or "make deinstall" respectively) is executed. In /usr/local/include
header files are _installed_ for accessing library functions, mostly
a means for programmers to interface with software.

But it's correct that you mention /usr/local/include/libpng/pngconf.h
here. It's not to be changed by "make configure", but it will be
created by "make install", reflecting the properties libpng has
been installed with; it's a "machine configurable file for libpng"
by its own declaration. It belongs to the png port, _not_ to the
port configuration subsystem (which is _independent_ from the
ports theirselves.
