I assume you are asking whether software solely licensed under
the quoted terms may comply with the DFSG.

This looks like a license specifically designed for one single software
package. Not a good start.
Personally, I would recommend the copyright holders to switch to
a well known and well vetted license suitable for releasing Free
Software (such as the GNU GPL, for instance).

This does not seem to meet the DFSG.
I think it fails to meet DFSG#3, because, if I choose to distribute a
derived work to the original sofware copyright holder, I cannot do so
"under the same terms as the license of the original software": I am
forced to grant them unlimited rights over my modifications, which is a
much more permissive "license" than the terms of the license of the
original software.

This looks non-free: it completely forbids binary distribution,
even when source is made available. It only allows the distribution
of a binary+source bundle.
This clause would even be violated by the Debian mirror infrastructure
(should GSAS-II be included in Debian), unless the source were bundled
inside the binary .deb packages (which is not the usual way software
is packaged for Debian...)!

You're welcome.
P.S.: Please note that what I expressed are my own personal opinions
and not an official statement from the Debian Project.
