Comment(by jhpalmieri):
If I comment out all assignments to {{{Kstd1_mu}}}, then Sage starts and
for the directory sage/libs/singular, there is only one doctest failure:
{{{
sage -t devel/sage/sage/libs/singular/option.pyx
**********************************************************************
File "/scratch/palmieri/sage-4.5.2.alpha0/devel/sage-
main/sage/libs/singular/option.pyx", line 415:
sage: J.groebner_basis(mult_bound=100)
Expected:
[x^3*y^2 + y^3*z^2 + x^2*z^3, x^2*y^3 + x^3*z^2 + y^2*z^3, y^5, x^6 +
x*y^4*z^5, x^4*z^2 - y^4*z^2 - x^2*y*z^3 + x*y^2*z^3, z^6 - x*y^4*z^4 -
x^3*y*z^5]
Got:
[x^3*y^2 + y^3*z^2 + x^2*z^3, x^2*y^3 + x^3*z^2 + y^2*z^3, y^5, x^6,
x^4*z^2 - y^4*z^2 - x^2*y*z^3 + x*y^2*z^3, z^6, y^4*z^3 - y^3*z^4 -
x^2*z^5, x^3*y*z^4 - x^2*y^2*z^4 + x*y^3*z^4, x^3*z^5, x^2*y*z^5 +
y^3*z^5, x*y^3*z^5]
}}}
Not surprising, since it looks setting the multiplicative bound wants to
set {{{Kstd1_mu}}}.
Is something like this an option, if we can't fix the whole problem?
