how to check out from an svn that requires "callback_ssl_server_trust_prompt" ?

edit

I'm installing Kinect Demos for DiamondBack,follow the instruction here: http://www.ros.org/wiki/mit-ros-pkg/KinectDemos/dback

and I get stucked on step 5:

Check out the mit-ros-pkg code, as well as other needed libraries using rosinstall:

rosinstall ~/kinect_demos /opt/ros/diamondback kinect_demos.rosinstall

I got error msgs like this

Installing https://svn.csail.mit.edu/mit-ros-pkg/trunk  to /home/azureviolin/kinect_demos/mit-ros-pkg
Failed to checkout from url https://svn.csail.mit.edu/mit-ros-pkg/trunk : callback_ssl_server_trust_prompt required
ERROR: Failed to install tree '/home/azureviolin/kinect_demos/mit-ros-pkg'
 Checkout of https://svn.csail.mit.edu/mit-ros-pkg/trunk version  into /home/azureviolin/kinect_demos/mit-ros-pkg failed.

So my question is, how to neglect this callback_ssl_server_trust_prompt and check out the svn anyway? Or, how to get this trust so that I can check out the svn?

I searched and found this https://code.ros.org/trac/ros/ticket/3169

it says "mit-ros-pkg has a self-signed certificate, which means that SVN creates a prompt for checkout. You can override this in svn with '--non-interactive --trust-server-cert'. This doesn't seem like the right default option, but it would be nice to have an option in rosinstall that forces this. Otherwise we cannot rosdoc mit-ros-pkg w/o manually checking it out on every build machine "

but rosinstall doesn't have the option of "--non-interactive --trust-server-cert"

my OS is Ubuntu 10.04, with DiamondBack.

Thanks!
