[FGS] Unable to load dynamic library

[ssmith at refractions.net]

Hi Guillaume,  
  
Problem solv ... err ... somewhat temporarily worked around - if I change  
my /etc/selinux/config file to disable selinux (SELINUX=disable) then I can  
get to my maps and chameleon samples.  
  
However ... now I have a new problem :) On all but the very basic chameleon  
sample app I get a massive set of warnings (behind my map) along the lines of:  
  
Warning: imagepng(): Unable to open  
'/opt/fgs/tmp/ms_tmp/buttons/bec6572951315d47e28371658ffa6abb0.png' for  
writing in /opt/fgs/apps/chameleon-2.0/htdocs/common/buttonizer/buttonizer.php  
on line 637  
  
Other posts online point towards a lack of gd as the culprit ... libgd.2.so   
lives in my lib directory ... maybe it didn't make it into my php install -  
Thoughts ???   
  
Regards - Samuel
