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.

Comment:
I'm posting a new spkg, but not a perfect one. The flaw is that it is
version 1.1.4 rather than 1.1.5. I looked at 1.1.4 and 1.1.5, and (using
`diff -r ...`) I found two changes in the code: the file `src/C/dense.c`
was modified, and I imported that change into the 1.1.4 spkg. With this
change, it builds and self-tests pass on OS X Lion, and also on sage.math
and !OpenSolaris. So that's the version I'm posting here.
The other change was to `setup.py`, and I don't understand enough of the
changes in our patch to modify it. That is, `setup.py` in version 1.1.4
was almost identical to the version in 1.1.3, so it was easy to rebase our
patch, but I couldn't figure out how to rebase to 1.1.5. C'est la vie.
