Thank you very much for your prompt reply!! I was able to compile sage-3.4 on the OLPC XO. It took 3 days !! More than half of the time was spent in linbox, in particular compiling linbox-sage.C.
Since the XO tripped on the same ATLAS bug as Solaris, I removed ATLAS from sage-3,4 - slight modifcations to deps and to the spkg_install /setup,py of r, rpy and cvxopt. I also disabled the graphics login as suggesed in the sage wiki FAQ, The XO has 256MB of physical RAM. I gave it 256MB of swap space. I am always amazed that sage incorporated so many different packages so seamlessly. In my little exercise with the XO, I studied sage- spkg and some of the spkg-install and setup files and am further impressed !! Thank you !!
