It build fine but the I/O is seriously bugged for me, at least for the
displaying of rational functions (but probably wrapping too)...
I paste this:
----------------------------------------------------------------------------------------------------------------------------------------------
k = var('k')
tmp = [rising_factorial(x,k)/falling_factorial(x,k) for k in range(5)]
pol1 = axiom(tmp[1])
pol1
pol1
pol1
pol4 = axiom(tmp[4])
pol4
pol4
pol4
pol4
pol4
pol4
pol4
pol4
pol1 = axiom(tmp[1])
pol1
pol1
pol1
pol1
pol1
pol1
pol1

and get

Notice how when I ask for "sage: pol4" I first get blanks a few times,
then bits of the (presumably) internal representation, then what
should be displayed. And that pol4 keeps on coming when I ask for
"sage: pol1".
That seems like a first serious bug. It also hangs when I try to do
comvert SAGE rational functions to axiom rational functions without
displaying them.
