How to build manpages on OS X
Didn't see this documented anywhere, so...
If you want to do a full build of git on OS X including the manpages, you need the asciidoc and xmlto packages. Both of them are available from macports.org (formerly known as DarwinPorts) but out of the box, they don't work quite right. If you try doing a "make doc", you get the following error from xmlto:
I/O error : Attempt to load network entity http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
The superficial reason for that error is that xmlto is calling the xsltproc utility with a command-line option that tells it to not fetch documents from the network. If you edit xmlto and remove that option, the doc build will work, but it will have to fetch a bunch of files from SourceForge for every manpage, which is dog slow.
The real solution is to use local copies of the files it's trying to fetch. These files are installed as part of one of the dependencies when you install xmlto, but the install process doesn't tell the system where to look for them! To use these local copies, you need to do two things.
First, create an XML catalog file. Typically it's called catalog.xml. The contents should be:
<?xml version='1.0'?>
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> <rewriteURI uriStartString="http://docbook.sourceforge.net/release/xsl/current/"
rewritePrefix="file:///opt/local/share/xsl/docbook-xsl/" /> <rewriteURI uriStartString="http://www.oasis-open.org/docbook/xml/4.2/" rewritePrefix="file:///opt/local/share/xml/docbook-xml/4.3/" />
</catalog>
Yes, that second rewriteURI maps the 4.2 docbook URI to the 4.3 version -- blame the MacPorts packages, because that's what gets installed. The mismatch doesn't appear to hurt anything. (If you're reading this from the mailing list archive, MacPorts might have updated the packages since I wrote this, so adjust the paths accordingly.)
Now you need to tell the system to use the file. You do that using the XML_CATALOG_FILES environment variable, like so:
$ export XML_CATALOG_FILES=`pwd`/catalog.xml $ make prefix=/opt/local doc $ sudo make prefix=/opt/local install-doc
Annoying that it doesn't just work, but hopefully this will save someone some Googling around.

Sounds like a DarwinPorts bug (or lack of feature, or maybe feature still being added but not given to the public, I dunno).
My understanding is that these catalogs are maintained automatically by the distribution when stylesheets are installed. For example, on Debian systems, xml-core seems to offer the infrastructure and .postinst scripts for packages such as docbook-xsl use update-xmlcatalog tool to make sure the stylesheets they install are found locally on the system.
In any case, thanks for the write-up.

I've added a pointer to your message at gmane archive on Gitwiki page (GitDocumentation).

I'm using the ones out of fink, and it seems to work just fine.
