FreeBSD Port: subversion config

[Marcus Ahlberg]

Yesterday when I upgraded subversion from 1.4.2 to 1.4.3 with  
portupgrade I noticed that I couldn't restart Apache because the new  
version was built without mod_dav_svn.  This is because I originally  
built subversion with
make -DWITH_MOD_DAV_SVN -DWITHOUT_BDB -DWITH_SVNSERVE_WRAPPER install  
clean
and those options are not remembered by portupgrade. A manual build  
and reinstall solved the problem.

Some other ports use options that can be set when building the port  
for the first time or by running make config. I would like to se this  
in the subversion port to so that portupgrade knows how to rebuild it  
properly.
