GSSAPI auth stopped working after upgrade

Colleagues,

I have upgraded the svn client from subversion-1.6.17 to
subversion-1.7.2 on FreeBSD 7.4 and GSSAPI authentication stopped
working. svn does not even try to get a Kerberos ticket and tries to
use DIGEST-MD5 at once. The server is still subversion-1.6.16_1 (no
changes there).

What has happened and how can I get back my GSSAPI? Please help. Need
I now to enable something on the client side?

If I disable the digest-md5 mech on the server, like
(mech_list: gssapi anonymous), I get:

$ svn co svn://big/configs
svn: E210007: Unable to connect to a repository at URL 'svn://big/configs'
svn: E210007: Cannot negotiate authentication mechanism

# ldd `which svn` | egrep 'gss|sas'
        libsasl2.so.2 => /usr/local/lib/libsasl2.so.2 (0x281fc000)
        libgssapi.so.9 => /usr/lib/libgssapi.so.9 (0x284de000)

This is what happens on the net:
