Subversion apache module will not load in unstable

[Fraser Campbell <fraser@wehave.net>]

Hi,

I've been running subversion on an unstable server for quite a while. A while 
ago (over a month I'd say) it stopped working following an upgrade.  
Subversion has been through a few upgrades in the meantime but still willl 
not load.  Here's the error message that I get:

    Restarting web server: Apache2Syntax error on line 2 of
        /etc/apache2/mods-enabled/dav_svn.load:
    Cannot load /usr/lib/apache2/modules/mod_dav_svn.so into server:
        /usr/lib/apache2/modules/mod_dav_svn.so: undefined symbol:
            svn_pool_clear

Line 2 of /etc/apache2/mods-enabled/dav_svn.load is simply this, there is only 
one other line in the file and it is commented:

    LoadModule dav_svn_module /usr/lib/apache2/modules/mod_dav_svn.so

These are the relevant (I think) packages installed:

ii  subversion     0.30.0-1       Advanced version control system - in develop
ii  libapr0        2.0.47-1       The Apache Portable Runtime
ii  libsvn0        0.30.0-1       Subversion shared libraries - in development

Anyone know if this is something local to my installation?  Server is a 
completely up-to-date unstable on i686.

Thanks,
