Comment (by Snark):
I don't insist on running "sage --kash".
I ran "make ptestlong" and it tried to run things using "sage
--something".
Kash wasn't the problem ; I don't remember if it was ecl or scons... or
something else... Of course the test failed : even though I made sure in
sage-env it had what it takes in the PATH, the script didn't even see it!
I claim sage-as-it-is is broken because it can't accept a small change in
a place without breaking in an unrelated place for no serious reason.
My patch doesn't break sage-as-it-is, and makes it more easy to modify in
the future: tomorrow, you'll decide to put the executables in
$SAGE/whatever/bin instead of $SAGE_LOCAL/bin. Of course, you'll modify
sage-env to cope with the change. And it will still not work. Why? Because
that script doesn't care about sage-env, it does it's own thing... and I
claim that is wrong.
My patch makes it possible to change where sage finds executables in one
sensible place instead of several.
I'm not telling you: "There is a theoretical issue, drop everything you do
and work on it for me!". I'm telling you : "I made private changes, hit a
practical issue, and even though you might not have met it yet, there's a
chance you will, and here is a simple nice fix."
Does it sound that unreasonable?
