i am trying to install the following plugin:  
[http://agilewebdevelopment.com/plugins/acts\_as\_taggable\_on](http://agilewebdevelopment.com/plugins/acts_as_taggable_on)

it recommends doing by the new gemplugin for ror by adding the  
following in environment:

config.gem “mbleigh-acs-as-taggable-on”, :source =\> “http://…” etc.

which does not work for me because i can not start my app anymore

so, installed the gem directly with gem install …

but i can not get my app to recgnize the gem. i have tried to insall  
everything as a plugin but now trying a gem a out.

i thought maybe it required a require statment in the environment file  
but that does not work either.

so what doesn’t work? do you get any error messages? post them…  
I’ve used iit as a plugin several times without any trouble.

you need to restart the server after installing the plugin…

not  
acts\_as\_taggable\_on
