I fail to see the point of all this, if you need cyrus it should be 
enough to just do, without any modifications:

SASL=cyrus ./postfix.SlackBuild

Alan included my patches for cyrus into postfix slackbuild some time 
ago, and afaik it should work fine, I run the same on a few of my mail 
servers. Altho I would have also preffered if he went with cyrus as a 
default option, since it comes in stock slackware, he is also 
maintaining a dovecot slackbuild, so I guess it is just easier for him.
Or do I completly fail to see what you are talking about? :-)
