Ack, my current approach uses a new flag in lookup_info structures to
mark lookups which are compiled as shared objects. It tries to load a
referenced lookup, when search_findtype is called and unsets the flag on
success . When it can't load the needed .so it will fail with a lookup
unknown error. So it's transparent to the enduser, and the packager only
needs to build packages for the .so and maybe some symlinks (for modules
with more than one lookup-type like ldap).
