It's not only about 1 gig --- first it takes long time to download for
me, it takes about 30 min to unpack on my slow laptop, but that could
be overcome -- a big problem is that Sage doesn't build on our cluster
(some problems in some math packages, that I don't need), that's a
showstopper. SPD does build there.
Plus I want to create custom all in one solutions for our code, e.g.
for PDE, so the result will be much more than 1 gig after including
all the custom code (e.g. all solvers, etc.).
