Here's a plan:
{{{
Fixing this is on the todo list, and I hope it happens for sage-4.1.1.
Mostly atlas and mpir are the only two packages that "cause trouble",
though I'm not convinced of that -- I tried building a binary on sage.math
(on a 32-bit vmware machine), then putting it on an *old* Pentium withouts
ssse3 pni, and it of course wouldn't start. Then I rebuilt atlas and
mpir, and it seemed to work fine. I then ran the test suite, which did
*not* come close to passing -- so other things evidently fail. If anybody
wants to help with this, the plan is the following.
1. Fix the atlas and mpir spkg's so they definitely support the
SAGE_FAT_BINARY environment variable (this might be the case already).
2. Build sage binary using the SAGE_FAT_BINARY variable set on a modern
32-bit linux box.
3. Move that binary to an old 32-bit linux box.
4. Try it out -- if it fails to start then the SAGE_FAT_BINARY flag
doesn't work. Go to 1.
5. If Sage starts, try "random_matrix(ZZ,300).det()", which will test
ATLAS. If this fails, go to 1.
6. Run the full Sage test suite. Inspect and see what is still built
using ssse3/pni, etc. Go to 1.
