Comment:

 The file /opt/local/share/ghostscript/8.71/lib/pdf2dsc.ps  is part of the
 port ghostscript, not part of the port gv.

 What do you mean "the bug is principally known"? Known by whom? Is there
 an upstream bug report? If so where? Where did this patch come from? Is
 this an upstream fix? If you invented this patch yourself, have you
 already reported it to the developers of ghostscript?
