gdchart PECL module is broken against current gd library

[geofft]

busy-beaver:~/web_scripts geofft$ php
<?php
dl("gd.so");
dl("gdchart.so");
PHP Warning:  () dl(): Unable to load dynamic library '/usr/lib64/php/modules/gdchart.so' - /usr/lib64/php/modules/gdchart.so: undefined symbol: php_gd_gdFontMediumBold in - on line 3

It looks like this is fixed by ​this patch to php-gd, which exports the necessary symbols -- but this requires a recompile of the php source package. It also looks like ​the gdchart PECL extension hasn't been updated in quite a while, so the bug may lie with it, in accessing internal symbols.
