There is quite a bit of discussion going on at ticket http://trac.sagemath.org/sage_trac/ticket/4890 about nauty's interactive installation that demands that a user agree to a license. I originally made that spkg and the result of the discussion at that time was that an interactive license was needed. There is strong disapproval of having an interactive license now. The end of the discussion on the ticket points to having a thread on sage-devel to address the question. For your convenience, here is the last comment:
"> I would still not call this interactive error message "stupid" since > it was done deliberately. "I think interactive license agreements are annoying. They are all done deliberately. "> Nauty is not only non-free, but its license prohibits its use for > works involving primarily military applications, so this is not about > non-GPL vs. GPL. "Nauty is free as in beer, but the free license it is under is not "libre" i.e., not OSI approved and not GPL-compatible. Nauty's license is: "Permission is hereby given for use and/or distribution with the exception of sale for profit or application with nontrivial military significance." There are essentially no other restrictions. "Since we have a fundamental disagreement here, this will need to be discussed on sage-devel and possibly voted on." Note that in this case, apparently nauty is included in an (optional?) package we install with gap, so at least there is inconsistency here. Does someone (William?, mabshoff?) want to explicitly state the proposal we are voting on? Personally, I don't care either way. I guess I've been weaned off of nauty for a while now, thanks to Robert's good code :).
