You can use "ldd" on the generated binary to see if it links against the 
library or if (somehow) a static version was compiled into your binary.  
However, I suspect what's really going on is that one of your binaries has 
debug symbols (compiled with -g) and the other does not (and both are linked 
against the shared library).

Best,
