dlopen will cause you to break at runtime instead of buildtime if

You should expect things to break when you change an interface - pretty
much by definition. If it hurts, don't do it.
I was discussing a case where instead of linking against libvorbis, you
dlopen() it - that's the sort of thing which is really much better to
catch at buildtime. If you're dlopening the plugin that is itself linked
against libvorbis (or whatever), that's better.
Won't anything using a shared library break if you replace that library
with one that does not follow the same interface definition whether it's
dlopen()ed or not? That's kind of the whole concept of interfaces -
they aren't supposed to change. If you write a new one, call it
something else.
