I know how to fix "my" problem, I just don't know how to fix Sage.
To the top-level *Makefile* that is. ('?=' is not [ba]sh syntax AFAIK.)
(And I originally only wanted to add an additional target 'upgrade', setting
the variable to 'yes' and depending on 'build'. When 'yes' is the default,
I don't know what the opposite target should be called;
'quick-and-dirty-upgrade-not-really-rebuilding-dependent-packages' perhaps,
or 'unsafe-rebuild'.)
Why would we need a buggy upgrade script ?
Backwards compatibility. And I personally don't want ATLAS to get
rebuilt just because someone decided to change the spkg-install script
of readline such that Python gets rebuilt upon which unfortunately ATLAS
depends, just because its spkg-install is a ***** Python instead of a
shell script. There are lots of similar situations [where you know
rebuilding isn't necessary].
