 Replying to [comment:15 ncalexan]:
 > This segfaults on startup for me with sage-4.0.1.  I thought the patch
 at #6051 might help, but it doesn't apply against 4.0.1.  We want to merge
 this in 4.0.2 so quick movement is appreciated.

 What did you do in order to install the spkg?

 You should do:
  1. Either replace the singular-3-0-4 spkg by the new spkg and re-build
 Sage ''from scratch''
  2. Or do the following:
       i. ``sage -i singular-3-1-0...`` (so, install it into an existing
 sage)
       ii. ``sage -f ntl...`` (so, force a re-installation of the ntl-spkg)
       iii.
         * Do ``sage -ba``, or
         * touch all Cython extensions depending on Singular (these are
 sage.libs.singular.singular, sage.matrix.matrix_mpolynomial_dense,
 sage.rings.polynomial.multi_polynomial_ideal_libsingular and
 sage.rings.polynomial.multi_polynomial_libsingular) and do ``sage -b``

 This is how I installed the new spkg.

 Cheers,
     Simon
