	My guess is that the ‘libpng-config’ executable coming first in
	your $PATH is still the one belonging to libpng15, not libpng16.

	What’s the output of $ type libpng-config?  Do that file’s mtime
	and ctime (try $ stat on the file) reflect the date and time the
	new version was installed?

	If it’s indeed the “wrong” libpng-config which gets used, –
	check the value of the $PATH environment variable itself and
	either adjust as needed for the directory with the “right”
	libpng-config to come first there, /or/ somehow prevent the
	“wrong” file from being found (either $ chmod a-x it, or perhaps
	rename it.)
