I am trying to install an application on the TKL Lamp Stack which requires the addition of the ZendGuardLoader runtime, which is a shared library (.so) file.  However, I can not seem to get the TKL system to recognize it.  

Where should I place the shared libraries so that PHP can pick it up?  I found some others like GD and mysql in /usr/lib/php5/20090626.  I put it in there, created a new .ini file in /etc/php5/conf.d and put the proper lines according to the doc in there...

but still no luck.  

Any ideas?

TIA

[SOLVED]  Needed to use the 64 bit version of the library, and now it loads properly and is recognized.
