persisting problems with pdf display in `gv': error /undefined in copy_trailer_attrs

[j. van den hoff]

hi,

FYI: after doing a `port selfupdate; port upgrade outdated' this bug  
surfaced again, i.e. it is still not patched
in the macports `gv' package.

if I knew how to do it I would help out, but I presume it's easy for  
someone from the macports core group (one-line
patch to /opt/local/share/ghostscript/8.71/lib/pdf2dsc.ps).

regards,

joerg
