I get the same exception on both Intel and Arm when I try to import 
sage.all from the sage python.  There is no exception if I do the same 
import in sage -python.  But that is no help in terms of running lldb.  
However, perhaps if I knew how to set up the correct environment first I 
would be able to start the sage python in lldb and then actually be able to 
do the import.
