In November 2006 sourceforge changed the svn access url from svn.sourceforge.net to pkgbuild.svn.sourceforge.net http://sourceforge.net/docs/E09#notice
I think sourceforge.net recently dropped support for the old url (svn.sourceforge.net) and this is what people are seeing. To fix it, checkout your source using pkgbuild.svn.sourceforge.net and you won't need the network hacks. This message posted from opensolaris.org
