I've finally gotten around to setting up a subversion server on my network and it's working really well, from my Vista machine.
But I really like my MacBook and would like to get it working there as well. So I downloaded SVN and installed it where it was dumped into the /opt/subversion/bin folder. There was already an older version, 1.4, in /usr/bin. Netbeans and svnX both allow me to set the path to the svn binary so they're working ok. But I can't find where to set the path in SCPlugin and it seems that the plugin would work better for me than svnX.
