It may not make a lot of difference, but I am now wondering how to
recognize an "error reported by pkg_add" since this:

> > pkg_add: command '/usr/local/bin/xmlcatmgr -sc /usr/local/share/sgml/catalog.ports add linuxdoc/catalog' failed

looks like one to me, but apparently it isn't.

I didn't find anything pertinent in the (minimal) installed
documentation.

Just taking the xmlcatmgr message at face value, it looks as if
some addition that linuxdoc intended to make in some catalog did
not get done.  Anything following that step in the postinstall
script may also not have gotten done.  My gut suspicion is that
there is something wrong with the linuxdoc postinstall script
-- or perhaps linuxdoc has an unstated dependency which I don't
happen to have installed -- rather than something wrong with
xmlcatmgr.  PR time, I guess :(
