Comment (by ryandesign):

 The point was that I would not want a port to declare a dependency on
 something it does not use, and I did not see evidence of epstopdf's use in
 the log, and I assumed that epstopdf is something that would be used
 during the build. The use of epstopdf only appears within the port's doc
 variant and the only types of dependencies added by that variant are build
 dependencies, which means they cannot be things that get used by the files
 installed by the port at runtime. I left these notes in this ticket in
 order to assist whoever picks it up next; I'm not investigating further at
 the moment.
