be GLP 3. But you might find you can only use the latest version which is
GPL 2, and not a GPL 3 version.

Fair enough.

Yes, it is. Sorry, I was not aware of the existance of that machine.
However, I do not know how the compilers and paths are configured on that
machine. You need to have GNU make & GNU tar in your path before the Sun
ones, and you need to have the Sun linker (/usr/ccs/bin/ld) in your path
before any GNU ones. There are some general instructions on building Sage
on Solaris at http://wiki.sagemath.org/solaris which you would need to
follow.
I've written some somewhat simpler instructions at
http://wiki.sagemath.org/devel/Building-Sage-on-the-T5240-t2 on how to
build Sage on 't2'. They are simpler, as I have already put the right
tools in the right locations.
The Sun Blade 2500 (mark2) should be quicker than the T5240 (t2) at
building Sage. However it would require some setting up of the build
environment to build Sage. If you just want an easy solution, 't2' will
just work, albeit not as quickly as the Sun Blade 2500.
