Can't invoke git-svn from command line

I just installed git on my linux machine (Kubuntu distro) by running the following command:

sudo apt-get install git-core git-doc gitweb git-gui gitk git-email git-svn

I would like to migrate a project which currently uses subversion to git. But if I run git-svn I get the message : git-svn: command not found

Any way to fix this?

Thank You.

The (new) interface to run git-svn is actually:

$ git svn <command> [options] [arguments]

(notice the lack of -)

sudo apt-get install git-svn

This command does it all in Ubuntu. Your distro (example yum install) can probably do it.
