I'm not thinking about other packages provided by pkgsrc, but generally 
programs supplied with sourcecode.

The code may include <libpng/png.h> and generally link with -lpng, 
configure will check for some locations but the structure is this usual 
one. NetBSD used to comply to this too by providing some links. I think 
it is a bug that the current libpng install is not done in this way 
anymore, but perhaps it was done with some good reason?
