I believe the Rice BSD Software License of arpack violates the Debian Free
Software guidelines (I've included it below for convenience of reference).
Both parts of the fourth clause of the license below seem to violate the
DFSG. The first violates the standard Desert Island and Dissident tests.
I believe it has also been concluded in the past that requiring users to
cite software is not allowed, which the second sentence violates.
The third clause also seems to violate clause (4) of the DFSG, since it is
a restriction on distributing modifications other than the specifically
allowed restriction of requiring the separate distribution of patch files.
The ARPACK license is BSD-like.
