That was my first tack.  At this stage of the game on Ubuntu LTS, GTK+
relies on png 12.  You can have GTK3+ or png 16, but not both.   

Your suggestion may illuminate part of the root of the problem,
though.  Most packagers undoubtedly are running relatively new systems,
and have png 16 installed as a matter of course.  And most Anaconda
usrs don't situate the package in /usr/local.  

If I put my anaconda elsewhere or ran closer to the leading edge
(either one) my anaconda installation wouldn't have come into play,
because configure would have found /usr/local/lib/libpng16.so.  It's
only the combination that manifests the defect.
