--------------------------------

However when I try to run ruby script with extension, I get this error:

--------------------------------
Could not open library /Users/marek/Projects/noderb/noderb/ext/noderb_extension/noderb_extension.bundle - dlopen(/Users/marek/Projects/noderb/noderb/ext/noderb_extension/noderb_extension.bundle, 10): Symbol not found: _uv_timer_init1 (LoadError)
--------------------------------

On MRI it works just fine. Do I  have to do something special for Rubinius?
