you should have libpng15.pc and libpng16.pc now. What is the problem As 
you describe it it is not in the png package but in the cairo package.

I understand that you want cairo-dev always pick up the current png, but 
"record" which version it is using, e.g.  png15, so that when png16 
comes out it continues to work.

Perhaps rebuilding cairo-dev helps? Perhaps it is not natively possible.


As soon as I can upload the new png packages, the frist person that will 
rebuild cairo will need to update this:

BUILD_DEP_PKGS += CSWlibpng-dev
to
BUILD_DEP_PKGS += CSWlibpng16-dev

I will try that, but I don't know if it will "fix" the issue you are 
seeing, when libpng17 will be out.
