The simplest solution will be to build Sage from source. Feel free to post your hardware details and the binary build that you downloaded, maybe we can reduce the requirements.

2013-06-11 14:41:06 +0100	asked a question	Error when using elementary_divisors() Can someone please tell me what this error means? `***-macbook:sage faculty1$ ./sage ../H-nqk.sage> ../test5.out Traceback (most recent call last): File "../H-nqk.py", line 38, in <module> print A.elementary_divisors() File "matrix_integer_dense.pyx", line 2065, in sage.matrix.matrix_integer_dense.Matrix_integer_dense.elementary_divisors (sage/matrix/matrix_integer_dense.c:17905) File "gen.pyx", line 8525, in sage.libs.pari.gen.gen.matsnf (sage/libs/pari/gen.c:43676) RuntimeError: Illegal instruction` When I execute the program using the online notebook everything runs fine, so it must be a computer issue. This error occurred when trying to compute the elementary divisors of a 125X125 matrix. Strange thing is, when running the program using a smaller matrix there was no error. Would really appreciate any help.
