Mapserver/Mapscript 4.6 Compiling Problem

[Paul Servant]

I did have the PHP GD library installed but kaMap wasn't loading the 
library.  kaMap loads init.php which dynamically loads the Mapscript 
extension for PHP.  However there seems to be a dependency between the 
Mapscript extension and GD.  If GD is loaded prior to Mapscript the 
problem goes away.  I didn't restart our Apache server after installing 
the php-gd packages through Fedora.  I assumed that kaMap was loading 
the GD extension for me.  It does load the extension in tile.php but 
init.php seems to be called first creating the error.  I'm currently 
loading my GD extension in my /etc/php.d/gd.ini file instead of relying 
on kaMap.

How do I report this to so the problem can be resolved for future 
releases of kaMap?

Cheers,
Paul
