Some 2.x releases were build with gcc 4.0.4 since they added C++ code
that does currently not work with gcc 4.2.4 for example. So run
mabsh...@sage:/disk/scratch/mabshoff-sage-releases/tools$ pwd
/disk/scratch/mabshoff-sage-releases/tools
mabsh...@sage:/disk/scratch/mabshoff-sage-releases/tools$ source
gcc-4.0.4-env
Addding gcc-4.0.4 to PATH and LD_LIBRARY_PATH
before starting either 2.5 or 2.6. There was some problem with the
Fortran support in 2.7, so I never finished building it. Anyway, in
the end there ought to be wrapper scripts, but I haven't written
them ;)
If this helps here are 2.5 and 2.6:
mabsh...@sage:/disk/scratch/mabshoff-sage-releases$ cd sage-2.5/
mabsh...@sage:/disk/scratch/mabshoff-sage-releases/sage-2.5$ ./sage
