Comment(by SimonKing):
I did a forced new installation of the polybori spkg, then of the M4RI
spkg, and I also installed the patches. I get on mark:
{{{
sage: P.<a,b,c,d,e> = PolynomialRing(GF(2), 5, order='lex')
sage: I1 = ideal([a*b + c*d + 1, a*c*e + d*e, a*b*e + c*e, b*c + c*d*e +
1])
sage: B.<a,b,c,d,e> = BooleanPolynomialRing(5, order='lex')
sage: I2 = ideal([B(f) for f in I1.gens()])
sage: I2.groebner_basis()
---------------------------------------------------------------------------

}}}
Of course, it could be that the problem comes from the polybori spkg. That
would be unfortunate, since it is already merged.
