I reported something similar a few weeks back (no response, though):
after
a further `port selfupdate; port update outdated' the problem persists:
gv any_pdf_file
throws the ghostscript error:
/undefined in copy_trailer_attrs
and that's it. doing
gs any_pdf_file
works as does
gv any_ps_file
this is on 10.6 x86 powerbook with current macports and gv-3.6.9,
gs-8.71
any ideas?
Sorry you didn't get a response before, but it's probably just because
nobody knew how to help you. You may need to ask the developers of gv
for assistance.
ryan,
I followed your advice, contacting the `gv' maintainer, who thankfully
responded quickly and to the point:
this is not a `gv' bug but rather a bug in ghostscript 8.71. the affected
file is at (for macports):
/opt/local/share/ghostscript/8.71/lib/pdf2dsc.ps
and here is the diff to patch it:

after this patch `gv' displays pdf just fine as it used to do.
I think this should of course be patched upstream, but if this does not
work right now, it should be done during the macports install process
(sorry, I don't know
the internals of `ports', otherwise I would do it...)
thanks again and
best regards,
joerg
