upgrade conflict between subversion and apache2

[jerry@…]

I have run port selfupdate, and have current versions of subversion and apache2 installed. I get this error on apache2 startup:

httpd: Syntax error on line 103 of /opt/local/apache2/conf/httpd.conf: Cannot load /opt/local/apache2/modules/mod_dav_svn.so into server: dlopen(/opt/local/apache2/modules/mod_dav_svn.so, 10): Library not loaded: /opt/local/lib/libaprutil-1.0.dylib\n Referenced from: /opt/local/apache2/modules/mod_dav_svn.so\n Reason: Incompatible library version: mod_dav_svn.so requires version 6.0.0 or later, but libaprutil-1.0.dylib provides version 5.0.0

Thank you for your yeoman work.
