I also have no problem upgrading from 2.1.22 to 2.1.23, on Mac OS X  
10.4.11 Intel with Xcode 2.5 and MacPorts 1.7.1.

But if you downgrade your cyrus-sasl2 to 2.1.21 first, then try to  
upgrade, you should get the failure I got (see below).

Presumably the ABI changed between 2.1.21 and 2.1.22 but not between  
2.1.22 and 2.1.23, and as we see it's trying to link with the already- 
installed older version of the libraries before trying to use the  
newer ones it just build (-L/opt/local/lib appears in the link  
command before -L../lib/.libs).

/bin/sh ../libtool --mode=link /usr/bin/gcc-4.0  -Wall -W -O2  -L/opt/
