Assuming that you used --enable-shared. Otherwise, there shouldn't
be a shared library.

Also, you'll have to stay away from --enable-shared to avoid the
absolute path that is required in an executable to refer to the shared
library. (As far as I know, here's no easy way in Linux to have a
relative reference from an executable to a shared library.)
