I exchanged email with Professor Sorensen and explained the issue
with the current ARPACK license.  

He is definitely concerned about this and committed to do the work to
relicense.  This will be no small amount of work for him so I want to make
sure we get it right. 

His intent is that ARPACK should be able to be used everywhere LAPACK
is used and suggested licensing it that way.  My understanding is that
the current LAPACK license is exactly the 3-clause BSD ("modified
BSD") so that is what I suggested.  T

Please let me know if there is anything I am missing here.
