Comment (by tlockhart1976@…):

 Replying to [comment:5 mojca@…]:
 > I committed r144343 with the changes because that was really the last
 port that needed the upgrade to 5.22. But we need to figure out what's
 with all those failures that I'm experiencing.

 You have entries in /opt/local/etc/sgml/catalog which point at files which
 do not exist on your system. I have the same entries, but have the files
 in question (e.g. /opt/local/share/xml/docbook/4.2/docbook.cat).

 The problem with "is not a function name" is due to a missing secondary
 XML or SGML catalog.

 Several SGML and XML ports reference these catalogs, and formerly they had
 a bunch of duplicate (or nearly duplicate - ugh) code which tried to
 manage these catalogs. A while ago I modified these to use the
 "xmlcatalog" portgroup to consolidate this duplicate code. I would expect
 that these catalogs get consistently augmented and diminished when ports
 are installed or removed, but extra duplicates are not detected and are
 not removed. I'm guessing that you have an inconsistent set of catalogs
 dating from before the use of the portgroup.

 Unfortunately there is no "foundational port" which owns the catalog
 skeletons, so there is no mechanism to remove them entirely from within
 the port system. That is, there is no port which knows about the state of
 other ports or can assume that if it is uninstalled it can completely
 remove the catalogs in question. Any suggestions there would be
 appreciated.
