Comment(by jhpalmieri):

 I think that in sage-starts, if Sage fails to start, you should delete
 `SAGE_ROOT/local/bin/sage-flags.txt`: this is created by sage-location,
 which gets run by sage, which gets run by sage-starts.  That is, the file
 sage-flags.txt might be created successfully, then
 {{{
 spkg/pipestatus "./sage -c \"print 'Yes, Sage starts.'\" 2>&1" "tee -a
 start.log"
 }}}
 fails, and then if you run "make" again, it won't test whether Sage starts
 because of the presence of sage-flags.txt.

 Either that, or there needs to be a different test in the Makefile to
 decide whether to run sage-starts.
