Heads up: New pgAdmin dependency

As of about 30 minutes ago, the SVN trunk version of pgAdmin requires an
additional package to build, namely wxAUI-0.9.2.

wxAUI can be found at http://www.kirix.com/community/wxaui.html. It is
essentially a pretty cool docking library that I've used to give pgAdmin
a much more modern and configurable look and feel.

If you build on Windows, simply add a wxaui directory to your
pgadmin-deps directory, containing a build of wxAUI in the
configurations you prefer. Unicode and Unicode Debug are normally
enough. You might want tweak the browse information in the debug build
to silence a warning when linking with pgAdmin, and additionally, you
may need to turn off manifest generation.

On Linux/FreeBSD/Mac/Solaris, simply unpack the wxAUI source into
/usr/local/src/wxaui-0.9.2. pgAdmin will find it and build it itself.
Don't bother trying to build using the wxAUI build system as it doesn't
allow multiple parallel builds as most of us use with wxWidgets. If you
prefer to use a different directory, you can pass
--with-wxaui=/path/to/wxaui to pgAdmin's configure script.

Hopefully this will be the last dependency we'll add (this cycle at
least!). If there are any problems, please post them to the list.

Regards, Dave.
