Note that people packaging Sage for Debian, Arch, NixOS are active here: https://groups.google.com/forum/#!forum/sage-packaging You can also have a look at say Debian sagemath package: https://packages.debian.org/sid/sagemath Sagemath packages which are "straight" C/C++ libraries may be installed (mostly) using the usual `make install` targets, I suppose (with appropriate --prefix set at configure stage (replace/change calls to sdh_configure by something else) You might like to replace calls to sdh_install, sdh_make_install etc in spkg-install.in to something like `make install`.
