Now, after many days, i succeeded in installing Sage on Tinycore.

Sage is a very mighty, and big (1.5GB if not in the tcz) math software, which is already near its proprietary competitors (Maple, Mathematica, Matlab...)

I want to share how i installed it: (btw: puppy sage-sfs-files are not working)

Download the binary tar.lzma release from the sagemath website: sage-4.7-linux-32bit-ubuntu_10.04_lts-i686-Linux.tar.lzma,

extract it, set SAGE_ROOT="/home/wstein/build/sage-4.7" in the sage script in the extracted sage-folder, (optional: delete sage-flags.txt in sage-folder/local/lib if you really want to ignore processor flags). Create a .tcz (requires of the sage.folder and mount it to: /home/wstein/build/sage-4.7 (or create a absolute path tcz and just add it to tce/optional like recommended for tinycore), add a new version of libgfortran.3.so to /usr/lib,(dont forget to add to /opt/.filetool.lst) and start sage

. Notebook works too.
