   I am not sure I understand your question. What I describe allows one to
install the Sage executable under /usr/local/bin, and launch it from
anywhere, provided that /usr/local/bin is in your path. You would only
invoked ./sage from /usr/local/bin, but - why would you want to that?

   That integration is nothing but a very basic functional test of the
installed product. I just used the Debian package - I did not build Sage
myself, for it takes ages and a serious system. I am merely pointing out
that, following the steps I described above, one ends up with a Sage
environment that seems to work fine, and one does not have to suffer the
punishment that the original maintainer described in order to install it in
a sensible location. I have tried a few other things in the resulting Sage,
and they all seem to work.
