This is a quick wrapper around Bruce Verderaime's gdchart C library.
The library itself is included here as it needed some gentle massaging
to get it to mesh nicely with PHP.  More info on the library can be had
here: http://www.fred.net/brv/chart

I have only tested this extension against PHP-4.3.x using the bundled
libgd in PHP's gd extension.  To build against such a setup you need
the PHP-4.3 sources available.  Then type:

 phpize
 ./configure --enable-gdchart=/home/rasmus/php43/ext/gd
 make
 make install

Change the path to your php43 source accordingly, of course.

If you get errors about GDC_title_font being undefined, make sure your
php_config.h file includes the various GD defines including 
HAVE_LIBFREETYPE.
