Hi Ryan,
As of Mon Jul 28 18:41:48 CDT 2014, I was able to download mlpack-1.0.9.tar.gz
using the direct link you posted. However, the mlpack main page at
http://www.mlpack.org/ also shows this menu entry for getting mlpack 1.0.9:
download
mlpack 1.0.9
released july 28, 2014
history and news
gsoc student blog
But when I click on "download" I get mlpack-1.0.8.tar.gz, not mlpack-1.0.9.tar.gz.
Looks like you need to fix this link.
Thanks,
-- Dave Slate
