Hi Jack. Not sure what is going on here. There were no changes at all in
the linalg module and the release was made the exact same way as the 0.13.0
release (on OS X 10.6, but that should not matter in this case). So I
suspect that either this is an intermittent failure or you changed
something on your end.

Did you install from git or from the zipped source release? Any change in
compilers you used?
