Thanks, now my matcher did get included. However, I'm trying to use  
have_tag (as in http://gist.github.com/46868), and I get this error:
undefined method `have_tag' for #<Matchers::HaveNotice:0x2e4a5c8>  
Any ideas on how to make have_tag available in my custom matcher?

Not particularly useful in this case, but if I have some spare time  
today, I'll try to update the docs.
