"pkg install subversion" tries to install multiple subversion versions at the same time

[Mark Felder]

This is due to a package name conflict -- all subversion ports used the
same package name and they were complicated ports entangled with many
other ports. Mat fixed this recently. It should go away soon when the
packages are refreshed.
