Currently building portdowngrade package on a clean system will only install subversion 1.8 even if 1.7 is defined in make.conf with WITH_SUBVERSION_VER=17. Linked patch by Olli Hauer fixes this and will install either 1.7 or 1.8 as required for the run dependency. Patch: http://people.freebsd.org/~ohauer/diffs/portdowngrade_svn.diff
