Ahh, I didn't read your first email well enough. If you configure the
build so that those libraries are linked, then they will be needed at
runtime. I'm not aware of a way to disable functionality in binary
based on what runtime libs are available, but would be willing to make
that work with Cyrus is possible (pull requests welcome).
