Call to undefined function: bindtextdomain()

Hi I am running Suse Linux 8.2, Apache 1.3.28, MySQL 4 and PHP 4.3.3 - all installed from source as I couldn't get the necessary integration when using rpms. I have several production systems working with this configuration. However, I now need to set up another one, and this one can't find bindtextdomain(). I realised that to get this function I needed to compile php with the --with-gettext switch. So, my question is, having not compiled php with that switch in the first place, how can I get the functionality I need into PHP without breaking everything else? Just to re-iterate, I HAD to compile Apache, MySQL and PHP together from source originally to get all of the required integration. What I want to avoid is having to install all three again! Is this possible? Just for info, I used this guide the first time I set up AMP (http://www.devshed.com/c/a/PHP/The-Soothingly-Seamless-Setup-of-Apache- SSL-MySQL-and-PHP/) Thanks Mick
