run-octave doesn't get generated, other problems with making documentation

[Jordi Gutiérrez Hermoso]

At changeset 10992:88687577519f, besides also running into the texinfo
problem related to egrep, I have a weird thing where run-octave
doesn't get generated, resulting in this:

     Making all in interpreter
     make[3]: Entering directory
`/home/jordi/coding/build-vcs/octave/doc/interpreter'
     ../../run-octave -f -q -H
/home/jordi/coding/vcs/octave/doc/interpreter/mk_doc_cache.m doc-cache
../../scripts/DOCSTRINGS ../../src/DOCSTRINGS || { rm -f doc-cache;
exit 1; }
     /bin/sh: ../../run-octave: No such file or directory

If I do copy run-octave.in and fill in the variable names it needs, I get this:

     Making all in interpreter
     make[3]: Entering directory
`/home/jordi/coding/build-vcs/octave/doc/interpreter'

../../scripts/DOCSTRINGS ../../src/DOCSTRINGS || { rm -f doc-cache;
exit 1; }

     ../../run-octave -f -q -H -p
/home/jordi/coding/vcs/octave/doc/interpreter --eval "geometryimages
('voronoi', 'eps');"
     error: invalid value = custom
     error: set: invalid value for radio property "papertype" (value = custom)

     error:   /home/jordi/coding/vcs/octave/doc/interpreter/geometryimages.m

     make[3]: *** [voronoi.eps] Error 1

Ideas? Can anyone reproduce this? I'm doing an out-of-source build, as
you can glean from above, in case this matters.

Thanks,
