While "DASL" is clearly a typo, no, it makes no sense that Postfix 
would have a compile-time problem with Dovecot SASL.  In fact no 
linkage takes place.  Postfix communicate with Dovecot SASL over a 
socket, and the SASL implementation is entirely internal on the 
Dovecot side.

The compile-time setting merely enables the code in Postfix to 
communicate with that socket.

One might ask, why do you need Cyrus SASL if you have Dovecot 
installed?  Typically you do not; only in the less usual case of 
Postfix having to authenticate at an upstream relay, would Cyrus 
become necessary.

All the details are here:
