Problem with custom accounting module.

Well this has turned out to be some sort of linkage/compile issue. On 
the same server, I can build the shared library for our module from 
either the source tree from our application or the source tree from 
freeradius. Building from freeradius works. The other way does not...

Best I can tell the same includes and libraries are used. A ldd of both 
.so files show commonality though our app has many more referenced 
libraries. I wonder if we've got a namespace collision somewhere.

Anybody got a suggestion for where to look?
