Hmm, there is no such directory on my Mac, and indeed this recipe
does not work here. I tried to transpose it to MacPorts by
substituting /opt/local/etc/xml/catalog, which does exist --- but
the recipe still doesn't work.
I believe what is actually failing is that http://docbook.sourceforge.net
now redirects to https:, and the ancient xsltproc version provided by
Apple doesn't do https. What you need to do if you want to use their
xsltproc is install a local copy of the SGML catalog files and
stylesheets, preferably in the place that xsltproc would look by default
(/etc/xml/catalog seems to be the standard one). It would be good to
document how to do that, but this patch doesn't do so.
What we do actually have already is a recommendation to install
appropriate MacPorts or Homebrew packages:
https://www.postgresql.org/docs/devel/docguide-toolsets.html#DOCGUIDE-TOOLSETS-INST-MACOS
and it works okay for me as long as I use MacPorts' version of xsltproc.
