OK, I just remembered it as having been quite recent, and the person asking
said he was using 6.1.1 so I (wrongly) assumed that the construction did
not work in 6.1.1. Only trying to help.

if your 6.1.1 came as a binary, this makes no sense - just get a new
binary.
otherwise - well, yes, but this is not so trivial.
if you got the source code via github (say), then you will need to
use git to

I've downloaded and installed the sage 6.1.1. But the program does not
recognize splitting_field . For example
sage:R. = PolynomialRing(QQ)
sage:K. = NumberField(x^3 + 2)
sage:S. = PolynomialRing(K)
sage:L. = (t^2 - a).splitting_field()
sage:L
