You will need to compile them. Usually the compilation can be as simple as 1. unpack the archive, for instance "tar -xf <tar file>.tar" 2. cd ./<sage directory> 3. make <wait for about 2 hours if you have a corei5 or more recent machine.> 4. ./sage # to run sage On Wednesday, March 7, 2012 7:38:38 PM UTC+8, Rita Morgan wrote: > > since testing is a bottleneck where can I download Sage 5.0 (alpha)?
