 Here is a Portfile.diff and new patch to update ARB to 5.3.

 Comments are welcome for a better way to accomplish the patch-GDEHELP-
 Makefile.diff.  The problem that I am having is that ${configure.cpp}
 appears to be empty.  I put an explicit "cpp" in the patch to get the ball
 rolling, but there has to be a better way.

 Also note that many of the patches are no longer necessary because they
 were incorporated by the upstream developer.
