I think you miss my point. I know how to install  linux-c7-libpng. My
concern is why this whole set of ports was not already installed. I kept
adding one port after another, but I have no idea where that ends. The
ports  system should install all dependencies automatically. Since only a
single linux emulation port is a dependency, I guessed that linux-c7-gtk2
is the culprit, bu reinstalling it generated that odd message:

Looking at linux-c7-gtk2, I see "USE_LINUX=      atk gdkpixbuf2 pango
xorglibs". I have already re-installed atk and pango, but the others are
not installed. Since pkg shows that these are not installed, I would have
expected that building linux-c7-gtk2 to have installed them.
/usr/ports/Mk/Uses/linux.mk states "# USE_LINUX     List of Linux packages
to depend on." So I am baffled as to why these ports are not being
installed. (I have tried both portmaster(8) and a simple make(1).) Clearly
something is broken here and it looks a lot like the ports system, mabey
linux.mk.

It may be time for me to open a bug report.
