Include other components in clusters?

Hi All.

I have begun making a small library with a lot of handy architecture tools.
I would like to ask if anyone know if it is possible to solve this problem:

If I make a custom cluster which includes a custom component from another library (ex. Elefront or Kangaroo). Then I cant send it to a friend unless he has exactly the same components/libraries installed...

Can I somehow include a another component into the cluster and send it ?

Best regards
