Late to the thread but since it has not been suggested: Have you tried to statically link all libs?

Then use Frank Cox's suggestion to use printf's at location thoughout the source code.

I know it will be big (depending on the number of libs)
But this way you are sure that the compile is against a known (yours) set of libs!

Also have you recompiled it and given the new binaries to the customers?

Just an idea ..
