It depends.
Usually, the problem is that the program tries to use some internal
member of a png structure directly (e.g. png->foo) and the solution is
to use the accessor function instead (e.g. png_get_foo(png)).

Most packages in pkgsrc have been fixed already, so you can look for
patches there, or bug their upstream to fix it.
