Please look at the package again. It is not about whether or not it requires a license tag. It is about whether the package is redistributable or not. I think it qualifies for the later and therefore binary packages can be distributed. I read the license, and there is no "permission is granted to redistribute". Specifically it says: Copyright (C) 2003-2005 Lowell H. Miles and Jack A. Venbrux. Licensed to ICs Corp. for distribution by the University of Illinois' National Center for Supercomputing Applications as a part of the HDF data storage and retrieval file format and software library products package. All rights reserved. Do not modify or use for other purposes. [permission to use] which is permission to UI NCSA to distribute, but not permission to anyone else. The code is copyrighted, so therefore it may not be distributed. I realize that we're used to seeing negative terms in license, but under copyright law, if there's no explicit permission to redistribute, there's no permission. I suspect if you talked to the copyright holders, they would be willing to grant permission to redistribute. But that's different from actually having granted permission.
