That's not very friendly for people who aren't their own system
administrators.  It may take weeks for a sysad to get around to it. 
Besides, you know what's going to happen:  after the new grade is added,
you'll start trying to build again, discover some dependency you forgot,
and suddenly you need *another* grade.  If that means an extra minute of
compilation that time, you might curse; if it means having to run
another sudo command which takes a minute, you might curse twice;  if it
means waiting another month for the sysad to get around installing
something else, you'll probably give up.
