Hi Stan, Did you download * sage-5.8-linux-64bit-ubuntu_12.04.2_lts-x86_64-Linux.tar.lzma*<http://boxen.math.washington.edu/home/sagemath/sage-mirror/linux/64bit/sage-5.8-linux-64bit-ubuntu_12.04.2_lts-x86_64-Linux.tar.lzma> and untar that? That is not a from-source compile.
You can run sage -gdb instead of sage only if you compiled from source, and see what the output is when you run your code via that.
