execute procedure over dblink

I have a dblink from db A to db B.  I am inserting data into tables in db A 
from db B by selecting.  The link works fine.
 
I have just put a procedure in db B and I am trying to execute the procedure 
from db A , but I am getting an "insufficient privileges" error.  What am I 
missing?
 
 
thanks.
