How to install Ruby plugins at Dreamhost

I have written a ruby application on my local pc using the DateBocks engine, a ruby plugin.

I’m having a ridiculously difficult time getting this app deployed to Dreamhost. Their support told me that I can’t install plugins because ruby is shared, which I understand.

So I installed my own version of Ruby, and then Gem, and I still cannot install the plugin, getting the error below.

Is it possible to use ruby plugins on dreamhost? Do I need t install it on the server? Why won’t it work if I simply ftp my Ruby app over?
