I don't know *how* special your situation is. But certainly you do not
need to be "root" in order to build and execute Sage.
Just download the tarball in your favourite directoory in your home
tree (where you have write permissions), say, ~/foo/bar/, and build
sage there, hence:
 - go to ~/foo/bar/sage-4... (whatever version it is),
 - type "make"
 - go for lunch
 - after lunch, provided sage is built, edit the file "sage" in this
folder. What you need to do is to provide an appropriate value for
SAGE_ROOT, which here is ~/foo/bar/sage-4...
 - Then, still being in this directory, you can start sage by ./sage

In that way, you can easily have various copies or different versions
of sage in parallel, and they do not interfere with the Sage
installation of your sysadmin.

Of course, if you just do "sage", you would still get the sysadmin-
version of Sage, since this is in your path. But in any directory you
would be able to start your private copy of Sage by
 "~/foo/bar/sage-4..../sage"

I think this is quite common for sage-devels.

Cheers,
Simon
