Then, there should be no reason to use OOo's private copy of

config_office/configure to make --with-system-libxml at least the

switch (and its negation --without-system-libxml) completely for
Mac OS X, right?
Yes.
I tried to use --with-system-libxml with OOH680_m4 and I get:
checking for pkg-config... /opt/local/bin/pkg-config
checking for libxslt ... Package libxslt was not found in the
pkg-config search path. Perhaps you should add the directory
containing `libxslt.pc' to the PKG_CONFIG_PATH environment variable
No package 'libxslt' found
configure: error: Library requirements (libxslt ) not met; consider
adjusting the PKG_CONFIG_PATH environment variable if your
libraries are in a nonstandard prefix so pkg-config can find them.
The thing is I cannot find any libxslt.pc on my Mac.
In addition pkgconfig is needed if I use --with-system-libxml.
This is Mac OS X 10.5.1 on a Mac Intel Mini.
I think this is a deficiency of our config_office/configure.in:1.237.
When using --with-system-libxml or --with-system-libxslt (where the
former also implies the latter, anyway), configure checks for pkg-config
to get suitable values for LIBXML_CFLAGS, LIBXML_LIBS, LIBXSLT_CFLAGS,
LIBXSLT_LIBS. However, at least on Mac, there appear to always (at
least when Xcode is installed) be /usr/bin/xml2-config and
/usr/bin/xslt-config that could be called instead of pkg-config. (I
think those two executables are standard parts of the libxml2 and
libxslt packages, but I might be wrong.)
Using the general pkg-config instead of (or before) the specific
xml2|xslt-config has at least two problems:
For one, as Eric observed, it needlessly makes pkg-config a prerequisite
on Mac.
For another, it introduces a subtle problem in combination with building
moz via MacPorts: moz has as prerequisites gtk2 and libidl, which can
be satisfied by installing those two via MacPorts (which in turn also
installs MacPorts pkg-config, and many others, including libxml2 and
libxslt) and setting PATH to find MacPorts pkg-config in
/opt/local/bin/pkg-config when building OOo. Now, as MacPorts comes
with its own versions of libxml2 and libxslt, even though the system
already has (different versions of) them, pkg-config will use the
MacPorts versions, so that the resulting OOo installation set will link
against the libraries from /opt/local/lib, and not work properly when
copied to a machine that does not have those MacPorts packages installed.
Both problems can be worked around by changing configure to use
xml2|xslt-config instead of pkg-config (or resorting to the latter if
the former is not available or does not work). I used a crude patch to
verify this (see below), but I would be happy if somebody with deeper
knowledge of autoconf (Rene?) turned this into a clean patch.
