Subversion server with Apache on Mac OS X.6 Snow Leopard
Create /etc/apache2/other/svn.conf:
LoadModule dav_svn_module /usr/libexec/apache2/mod_dav_svn.so
<Location /svn>
DAV svn
SVNParentPath /Users/jerome/svn
</Location>
This will make the Subversion repository /Users/jerome/svn/toto available at http://localhost/svn/toto.
Update the repositories owner (otherwise commits would fail):
chown -R www:www /Users/jerome/svn/*
Restart Apache
sudo apachectl restart
