Install the Radrails plugin for Aptana Studio offline

I downloaded and installed the Aptana Studio free version. But apparently, to install the Radrails plugin for ruby on rails development you have to connect to the internet. I don't have internet on my machine right now. So is there a way I could download the installer from another machine and copy it over my existing Aptana installation?

Update: Found a link for download here (Access denied now)

• If you're able to actually install it on the machine with the Internet connection, then you can simply copy over the directory you installed it in. Eclipse installations are completely self-contained in their installation directories.

• I wrote down my duel with Aptana Rails - See if this helps you. There is a link on manual installation that may be what you're looking for.
