Linux does not have it's own libpng and neither do we. Most Linux
distros and us use libpng from libpng.org. I took a quick look at the
current libpng in the ports tree and it appears to have png_read_png().
With out seeing a Makefile for the ports system and some error output it
is hard to comment as to the specific reason stuff is failing for you.
Yes, but my money says
==
=CPPFLAGS= -I${LOCALBASE}/include
=LDFLAGS= -L${LOCALBASE}/lib
=GNU_CONFIGURE= yes
=CONFIGURE_ENV= CPPFLAGS="${CPPFLAGS}" LDFLAGS="${LDFLAGS}"
===
will help, it always(x0.999) does :-) It's one
of those things everyone knows about but no one
commits into Mk/* because we enjoy routine so
much.
