Many of the command line utilities now link libcyrus, where they didn't before, which can cause this difference (it is a static link).
Is there any way to make it into a shared library?
Yes, but why?
Just to reduce the size of the binary rpm. Not a very compelling reason, I know, but it doesn't feel good to ship a 6 MiB binary rpm instead of a less than 3 MiB one. Well, disk space is cheap nowadays.
