I am currently trying to get vr up and running on Ubuntu 12.04.2  
Virtualbox  
I am running ruby 2.0.0  
I have re-installed ‘builder’ gem thinking that that may be the problem.

Successfully installed builder-3.2.0

but when i try to run vr I still get the same error. Im pretty lost at  
this point any help would be appreciated!

(not sure if this matters but Im running Ubuntu on top of Virtualbox on  
a 2011 mbp i5 2.3)

Hi Scott,

You can edit the “vr” file in  
/home/scott/.rvm/gems/ruby-2.0.0-p0/gems/visualruby-0.1.2/vr to fix this  
issue.  
I edited the “vr” file to require “builder” instead of require  
“rubygems/builder”

Hi Clouds:

Should I make this change in all the versions of visualruby?

I don’t understand the implications of your change.

I have these four lines in the vr file:

require “rubygems/installer”  
require “rubygems/uninstaller”  
require “rubygems/builder”  
require “rubygems/specification”

Should I change them?

Thanks,  
Eric
