Okay, so one does want something other than the zeros. Thanks for
clarifying that.
But I have to say, I don't even get anything different on my OS X 10.6
Mac, yet it gets the right roots
{{{
sage: roots = eigvals(A)
sage: roots[0]
1.7724538509055159
sage: roots[1]
-1.7724538509055159
}}}
Is it possible you mistyped something around the `lapack_routine` spot?
