I hit this same issue. You will need to re-install librsvg2. It has a
linkage to the old libpng:
Shared object "libpng15.so.15" not found, required by "librsvg-2.so.2"
# locate "librsvg-2.so.2"
/usr/local/lib/librsvg-2.so.2
/usr/local/lib/librsvg-2.so.2.40.4
# pkg which /usr/local/lib/librsvg-2.so.2
/usr/local/lib/librsvg-2.so.2 was installed by package librsvg2-2.40.4

I found several ports that had links to the libpng15.so using "pkg_libchk
-o". That tool is part of sysutils/bsdadminscripts. I have found it to be
very rigorous and trust it a bit more than "pkg check -B". I did drop bapt
a note listing the ports I found linked to libpng15.so, but I may have
missed librsvg2 as I hit that one very early in the process.
