opendx-4.3.2_4 port

[Ross A. Beyer]

Hello,

You are listed as the Maintainer of the graphics/opendx port for
FreeBSD.  I'm writing because after installation of the port,
attempting to run opendx, resulted in the following error:

> dx
/libexec/ld-elf.so.1: Shared object "libdf.so.1" not found, required by "startupui"

The libdf.so library is a part of the science/hdf port.  Installation
of the hdf FreeBSD port then allowed proper function of opendx.

So it appears that the science/hdf port needs to be added as a 
requirement for the graphics/opendx port.  Thanks for maintaining
a nice piece of software.
