[Chameleon] PHP interpreter error with mod_perl installation

[Ivan Kautter]

List serv subscribers,

I recently installed mod_perl2.0 on Apache2 web server running under Windows 
XP home.  Since then my Chameleon-based web map application will not work.  
The application refuses to generate a map image and hangs at the loading 
image GIF and no map image is to be found in the tmp directory as well.  I 
then get an error message that says that the PHP script interpreter has 
encountered an error and asks to send an error report.  Standard Windows 
sort of thing.  The application was running fine before installing mod_perl 
and I can successfully run phpinfo.php which suggests that the web server 
can indeed access the PHP script interpreter, I think.  Has anyone 
encountered such problems with Chameleon or MapServer in general?  Thanks 
for any suggestions or assistance offererd.
