> Another concern I have is that the doctest might not be too good across
multiple platforms. It would never surprise me, if on another CPU, the
GLPK solver gave something like 6.2499999 instead of 6.25. Making the
doctest accept any value starting with 6.2 would be silly, as that could
allow huge errors to pass. But I don't know how best to handle this. This
seems a weakness in the way we doctest. Assuming the real answer is 6.25,
we really want something that will accept any x such that abs(x-6.25) <
1e-6 or something like that.

I'd not be too surprised if the answers came out slightly differently. My
Sun you tested on is not a SPARC processor, but an Intel Xeon.
Just tested on t2, on Sage 4.6, with SAGE_CHECK=yes, and the tests in
sage/numerical/optimize.py, all works.
(Actually, it already worked on PPC, which is also not an 80-bit floating
point, but only 64...)
Now waiting for OSX 10.4 results, and hopefully MacOSX Intel, too.
