Hi

When I use heckle with some classes I got this error message:

heckle Greeter  
/usr/local/lib/ruby/gems/1.8/gems/heckle-1.4.2/bin/…/lib/heckle.rb:10:in  
`const_get': uninitialized constant Greeter (NameError) from /usr/local/lib/ruby/gems/1.8/gems/heckle-1.4.2/bin/../lib/heckle.rb:10:in`to\_class’

What’s going on?

Thanks
