How does this show anything other than that most users have left the sasl
library in an unusable state on their systems?

No, they should not.  The whole point of SASL is to abstract away the
authentication methods - server packages should not be depending directly on
particular SASL modules.

This doesn't appear germane to the patch I've proposed, which has an ORed
dependency requiring only that *some* SASL module be installed.
