OK, that is what I thought. Thank you. > 2. Improve the "sage -i" command so that "sage -i B" works and gives > the newest version, i.e., so that one doesn't have to type "sage -i > B-1.1.p2.spkg". Hmmm, I don't think that is what I need. I have in mind installing FriCAS (=A) and some the FriCAS-Aldor-Interface (=B) (you know the problem with the Aldor license). The version number of B should be identical to the one of A. So in my case I must give that explicitly. > However, I'm open to other ideas. Ralf, what do you *wish* would be > the natural way to specify dependencies? Hard question. The only thing that comes to my mind is connected to PLONE (plone.org). Plone is written in Python and packages for Plone are distributed via the CheeseShop (http://pypi.python.org/pypi/). Plone is mangaged using "buildout". "buildout", as far as I understand is somehow a build system (similar to Makefiles---but that is oversimplified). Anyway, Plone comes with a file buildout.cfg which is supposed to be edited by the user/administrator and which describes the layout of all (additional) packages. Optionally, one can include version numbers. It might look like... eggs = elementtree borg.project>=1.0b1,<2.0dev (see http://plone.org/documentation/tutorial/buildout/installing-a-third-party-product). If no explicit version (or range) is given the system automatically retrieves the latest version from a number of sites (which can also be specified in buildout.cfg). I have no idea whether this "buildout" system can manage packages that are not written in Python, but maybe someone more familiar with Python can find out. Perhaps Sage might also switch to using the standard Python egg format instead of spkg. Again, I don't know too much about that, so just take it as a starting point for further reading.
