MacOS-X
-------

A `macport <http://macports.org/>`_ of lxml is available.  Try
something like ``port install py25-lxml``.

If you want to use a more recent lxml release, you may have to build
it yourself.  Apple doesn't help here, as MacOS-X is so badly maintained
by them that the pre-installed system libraries of libxml2 and libxslt
tend to be horribly outdated, and updating them is everything but easy.
In any case, you cannot run lxml with the system provided libraries,
so you have to use newer libraries.

Luckily, lxml's ``setup.py`` script has built-in support for building
and integrating these libraries statically during the build.  Please
read the
`MacOS-X build instructions <build.html#building-lxml-on-macos-x>`_.

A number of users also reported success with updated libraries (e.g.
using `fink <http://finkproject.org/>`_ or macports), but needed to set
the runtime environment variable ``DYLD_LIBRARY_PATH`` to the directory
where fink keeps the libraries.  In any case, this method is easy to get
wrong and everything but safe.  Unless you know what you are doing,
follow the static build instructions above.
