I don't see that error.  It may be that it is happening because you
haven't installed all the dependencies, but we try to make the tests
run anyway, just skipping the ones that can't work because of missing
dependencies.  So will you try to debug where it is coming from?
The first set of "Integrated test scripts" that are normally executed
are from the file src/DLD-FUNCTIONS/besselj.cc.  To run them outside
of "make check", please try the following

  ./run-octave
  ...
  octave:1> cd /src/tree/directory/src/DLD-FUNTIONS
  octave:2> test besselj.cc

(where /src/tree/directory is wherever your top-level Octave source
tree is) and let us know what happens.

I think this message is incorrect now.  Previously, we only used
ghostscript to generate some output formats when building the Octave
documentation.  Now it is used in printing as well, to convert PS to
various formats.

I changed the configure warning to be

  I didn't find ghostscript, so reconstructing figures for the manual
  will fail, and saving graphics in some output formats will fail when
  using Octave
