I attempted to install the “virtual domain extension” but got the  
following

I tried both the following versions and they both had the same error.

- virtual-domain-1.1 (from  
[http://dev.radiantcms.org/radiant/wiki/Extensions](http://dev.radiantcms.org/radiant/wiki/Extensions))
- virtual\_domain-1.2.1 (from  
[Index of /~benji/radiant](http://silverinsanity.com/~benji/radiant/)  
)
