Re: docbook v4.1.2 missing "catalog.xml". broken?

[PGNet <pgnet.trash+oasis@gmail.com>]

a bit more info ...

it seems that a developer @ the macports project addressed this,
providing a patch file,

 http://trac.macports.org/browser/trunk/dports/textproc/docbook-xml-4.1.2/files/catalog.xml

which, cp'd into my local v4.1.2 dir, enables xmlcatalog validation to
pass (i'm re-attempting a glib build atm ...).

the developer had, apparently, communicated with upstream about this issue,

 http://lists.macosforge.org/pipermail/macports-users/2007-June/003703.html

but afaict, there was no response.  and, clearly, there's been no
catalog.xml added to the 4.1.2 dtd online.
