If you want to experiment with having Sage actually build multiple packages at the same time, which could vastly speed things up since even the ./configure's will run in parallel, you can try the following. WARNING: I've tried this once a while ago and it did *not* work for me, and I didn't have time to debug all the problems, so it isn't supported -- you will have to fix things. That's why I've cc'd this message to sage-devel. 0. Start with a fresh Sage tarball. 1. Open the file SAGE_ROOT/spkg/install 2. Find the line time make -f standard/deps $1 and change it to time make -j 4 -f standard/deps $1 3. cd to SAGE_ROOT and type "make". Watch lots of things happen at once, then something eventually go wrong, probably because of subtle dependencies that are appropriately described in SAGE_ROOT/standard/deps. I think theory, by modifying the makefile in SAGE_ROOT/standard/deps appropriately, one could make the above work. This would be very useful to a lot of people, actually, since it would speed up building sage on smp machines.
