Errors "upgrading" cyrus-sasl2

[Chris Janton]

Is it "normal" to have to "force uninstall" a port before a new  
version can be provided?

MacPorts 1.600

admin at x:admin:123 $ port outdated
The following installed ports are outdated:
cyrus-sasl2                    2.1.21_0 < 2.1.22_0
admin at x:admin:124 $ sudo port upgrade outdated
Password:
Portfile changed since last build; discarding previous state.
