I can download the dataset without
problems on my Linux thinkpad. Perhaps
you can provide some more info (but I do
not know what ...) so I/others can
reproduce this strange error ...
Have you checked the time on the laptop
being correct and not set to e.g.
1970-01-01 01:29? In the past, I have
found ssl errors are caused by the time
being off on my laptop, as in the case
of a flat cmos battery.

Perhaps setting
options("ssl_verifyhost"=0, "ssl_verifypeer"=0)
helps? [1]
