if you execute command "yum search cyrus-sasl", you'll find that you have,
cyrus-sasl.i386 2.1.22-4 installed
and the lib and devel package. next is to find where is the location for version 2.1.23 which in my case is at /usr/local/lib and the file is "libsasl2.so.2.0.23". once you have it, you need to remove the old version (2.1.22) lib from usr/lib. the file is "libsasl2.so.2.0.22". remove the file and the symlink as well.
copy libsasl2.so.2.0.23 or create a symlink to /usr/lib/libsasl2.so.2.
voila...run "make test" again and it should work now.
hope it's not too late..
