It's not such easy because usually you cannot link DSO's against other DSOs
(i.e. shared libraries here). To solve the problem you either have to build
this MySQL module statically or build on a smart platform (usually all
ELF-based platforms are of this type where you can link a DSO against a DSO)
and use --enable-rule=SHARED_CHAIN.
