  I tried that already, thanks.  That's why I'm now suspecting it's some
kind of mismatch between the Rutter PPAs and the default (?) repos that
Travis uses.  It would be a little painful, but I could edit out the
rstan dependency and try the builds with and without Rutter's PPA to
test that hypothesis ...
