MyBook World + Crashplan headless install

I would like to do the following:

I hope to install CrashPlan to backup the USB drive I have plugged into my NAS onto the NAS (since it is seperate and not backed up elsewhere) but I am getting stuck with the install.

I cannot get past installation step 3.  Any help would be appreciated.
