It looks like you're not using the latest version of MacRuby, which  
introduced #method_signature (quite a few builds ago).

$ macirb
 >> class Foo
 >>   def foo; end
 >>   method_signature :foo, 'v@:'

=> nil
 >> Foo.new.foo
=> nil

Check with macruby -v if it reports 0.4 at least.

Also, it looks like you're not using the latest HotConsole sources.  
The call to #method_signature was removed (it was added to work around  
a bug in MacRuby trunk which has been fixed after).
