Fedora Core 6 system, PHP / MySQL...
PHP has been installed, but needs to be recompiled with more options:
I'm sure there are a few others I'm forgetting, I'll let you know (they would just be included in the ./configure command anyway)...I think sablotron and expat have already been installed - though you may need to re-install if they weren't done correctly. You will be given root access to the server for the change.
Remote administration is done via Webmin.
