If external hyperlinks from our documentation PDF to other files stop
working, we cannot make this the default way of building our
documentation.  The version of Ghostscript that is pertinent here is not
the development master but mainly the version used in GUB, and
secondarily the version of Ghostscript we expect to be current in
GNU/Linux or other distributions that build LilyPond natively.  There is
some settling-down time as they are unlikely to use any 2.19 version
(it's a development version, after all), but basically there needs to be
a reasonable chance of the Ghostscript versions being fine by the time
we release version 2.20.
