New description:
On OS X Lion, if you set `SAGE_CHECK=yes` and build cvxopt, some tests
fail and then it hangs before completing the tests. See
[http://sage.math.washington.edu/home/palmieri/misc/cvxopt-1.1.3.log] for
the install log.
CVXOPT devs claimed that Apple shipped a broken BLAS. But it turned out
that they cannot provide valid examples showing this; they did not adhere
to a de facto BLAS standard, and they agreed to fix the corresponding
CVXOPT bug quickly.
Thus we don't really need to build ATLAS on OSX 10.7, at least not until a
real proof of bugs is found.
