SASL auth failure, reported by Cyrus SASL as "no mechanism available"

From: Daniel Rall <dlr_at_collab.net>

When I run 'make svnserveautocheck', I'm getting the following error
for pretty much all tests which use ra_svn:

  svn: SASL(-4): no mechanism available: No worthy mechs found

This problem occurs when libsvn_ra_svn/sasl_auth.c's try_auth()
detects SASL_NOMECH, either from sasl_client_start() or its
handle_interact() function.

Malcolm reported the same problem back in last October, and Vlad
responded <http://svn.haxx.se/dev/archive-2006-10/0317.shtml> saying
that this error can occur if Cyrus auth plug-ins are missing from your
/usr/lib/sasl2 directory. For Malcolm's case, Vlad suggested that a
missing libanonymous.so was the problem. I have such a plug-in. What
else could be causing this problem?

Here's the contents of my /usr/lib/sasl2 directory:

libanonymous.la* liblogin.so.2@ libsasldb.la*
libanonymous.so@ liblogin.so.2.0.21* libsasldb.so@
libanonymous.so.2@ libplain.la* libsasldb.so.2@
libanonymous.so.2.0.21* libplain.so@ libsasldb.so.2.0.21*
liblogin.la* libplain.so.2@ smtpd.conf
liblogin.so@ libplain.so.2.0.21*

Here's more of the output from a test failure (authz_tests.py):
