Hello,

I tried to install the Tags extension  
([http://github.com/jomz/radiant-tags-extension/tree/master/README](http://github.com/jomz/radiant-tags-extension/tree/master/README)) with  
the Radiant master but I got the following problem :

[13:01][vincentp@vincent-peress-macbook:~/NetBeansProjects/myproject(master)]$  
rake radiant:extensions:tags:install  
(in /Users/vincentp/NetBeansProjects/myproject)  
rake aborted!  
Dependencies is not a module

(See full trace by running task with --trace)

Could it come from rails 2.1?

Thanks,  
Vincent

Vincent,

My apologies – master is very unstable now because of some major  
refactoring going on. I hope to complete some of it this weekend.  
You’re best off using 0.6.9 or a head just before the merge with the  
Rails 2.1 branch. Andrew vonderLuft recently ran into this problem and  
mentioned which commit he chose on the mailing list.

Acutally,  
This is a problem with has\_many\_polymorphs on newer rails versions.  
I’ve received a pull request to fix it but haven’t had time to test it  
out. I’ll try to do that today.
