Comment(by ryandesign@…):

 * r75955: add libpng 1.4 patch and libpng dependency (I did not apply your
 proposed changing of `#include <png.h>` to `#include <libpng14/png.h>`
 because it seems unnecessary; png.h is a symlink to libpng14/png.h)
  * r75956: consolidate post-destroot into destroot
  * r75957: use `file attributes` instead of `system "chmod"`

 Two of the things being made writeable (formerly using `system "chmod"`,
 now `file attributes`) are directories; fine; you want regular users to be
 able to put files into them. The third is a file called arb_tcp.dat, which
 lib/Makefile copies from arb_tcp_org.dat. This feels like a config file
 that the user is expected to edit; is that right? If so, we should not
 register the file to the port. Currently, any changes the user makes to
 this file are lost when they upgrade the port. Let me know and I can make
 these changes.
