It says 'active' is an invalid attribute.  This matches what gpart mangpage 
says under ATTRIBUTES .. it doesn't list 'active' as an attribute for the GPT 
partition scheme (but it does for other schemes).    I did try to unset 
'bootme' but that did not help either.  

Do I need the newer version of gpart to be able to unset or set it?
