[Openmcl-devel] freebsd 9.1 amd64

Source changes to the CCL kernel that were intended to fix the problem
were committed to the CCL trunk. I don't know whether or not you
compiled the kernel before trying to run it ...
The changes don't seem to have fixed the problem (where at least some
of the problem seems to have to do with AVX-related changes to the
format of signal contexts in FreeBSD 9.1.)
I have a core i3 machine (with AVX) that I should be able to install 9.1 on
and will try to announce something here when I'm really sure that I understand
what else is happening and how to fix it. Thanks.
