I'm compiling syslog-ng 3.2 beta 1. I'm going to update to 3.2 release 
briefly, maybe it's fixed in there? Even though I used:

--libdir=/home/opt/lib64

The syslog-ng plugins are still going into lib. I can't make an internal 
package of the app to use here until I figure out how to fix it. The 
files in question are:
