db2pdf: cannot generate system identifier for public text...

[Norman Walsh]

/ Chris Turchin <ct@sliceware.com> was heard to say:
| jade:sgmlTest.sgm:1:59:W: cannot generate system identifier for public
| text "-//Davenport//DTD DocBook V3.0//EN" 
| 
| and then a lot of errors since none of the entities are defined...

You need to update your catalog(s) so that one of them contains

  PUBLIC "-//Davenport//DTD DocBook V3.0//EN" "/path/to/docbook.dtd"

And/or update to a newer version of DocBook...

                                        Be seeing you,
                                          norm
