In your following message, you say “Unable to sagemath download pre-built
binary from site”. Is that literal output from tar? It’s pretty weird
phrasing, in the first place. And additionally, how does “it” know what the
site is, and that the tarball contains a pre-built binary?
So

You might try starting with this (unverified):
R. = PolynomialRing(QQ)
K=R.fraction_field()
S.=PolynomialRing(K)

And, in case you didn't know about these features of sage/python:

To clarify this, I believe that the man page says that .bash_profile is checked
for a login shell, and that .bashrc is checked for a non-login, interactive
