Building Sage on t2.math is possible. But wrapping up one's build into
a t2.math binary is hampered by the sage-bdist script using this
GNUism:
if [ $UNAME = "Darwin" ]; then
OPT="Rp"
else
OPT="ra"
fi
I'm referring to the option "a", which is passed to cp later on in
that script. With sage-bdist as is, I can't wrap up my build. But if I
remove the option "a", then there is some progress. A better approach
is to systematically go through the script sage-bdist and purge it of
GNUism. That way, the script would happily run on t2.math, and indeed
on Cygwin, Linux, Mac OS X, Solaris.

This should now be fixed by ticket #7943:
http://trac.sagemath.org/sage_trac/ticket/7943
which has been merged in Sage 4.3.4.alpha1.

On a related note, there really needs to be a bigger /scratch
partition or drive.
