Hi Matt.

I don't think macs have sha512sum. I get:

Awesome!  Here we go.

Using wget
Downloading HDF5
Downloading hdf5-1.8.7.tar.gz from yt-project.org

I am unable to locate sha512sum.  FILE INTEGRITY NOT VERIFIED.

Hi all,

Currently to verify file integrity with the install script we download
sidecar md5 file from yt-project.org.  These aren't versioned, and md5
itself is largely deprecated for this.

I've created a new sha512-using version of the install script, which
uses sha512 hashes stored *in the install script* to verify file
integrity.  This way any time these change we will be notified of
them.  I'd like it if a few people could test this -- I have -- on
pristine systems.  It changes both how the files are downloaded and it
now uses sha512sum, which should be available on most systems
(according to Kacper :).

You can do this by:

wget https://bitbucket.org/MatthewTurk/yt/raw/367ea3bfff2e/doc/install_script.sh

and then running it, but maybe supplying an alternate directory rather
than the default.

Thanks for any feedback.

-Matt
