New description:
We do have an optional GINV SPKG which comes with its own Python interface
but no interface to it from Sage.
With the attached patch, this now works.
{{{
sage: P.<x,y,z> = PolynomialRing(GF(127),order='degrevlex')
sage: I = sage.rings.ideal.Katsura(P)
sage: I.groebner_basis(algorithm='ginv') ...
[z^3 + 22*z^2 - 55*y + 49*z, y^2 - 26*z^2 - 51*y + 51*z, y*z + 52*z^2 +
38*y + 25*z, x + 2*y + 2*z - 1]
}}}
Please use the last patch, the 1st one has non-ASCII chars in it.

Comment:
Tested on Sage 5.0 beta2, Linux x86_64 Debian. It works.
