If the configure script doesn't support --with-png=/your/path/to/png,
then you can force feed it by using env vars. As in:
env LDFLAGS=-L/your/path/to/png/lib CPPFLAGS=-I/your/path/to/png/include configure
In your freebsd port, there is a common idiom that looks like this
in the Makefile:
LDFLAGS+=-L/your/path/to/png/lib
CPPFLAGS+=-I/your/path/to/png/include
CONFIGURE_ENV=CPPFLAGS="${CPPFLAGS} LDFLAGS="${LDFLAGS}
(see also bsd.port.mk and the Porter's Handbook)
ports@ is a better place to ask such questions, by the way.
