Jordi, I agree with your thought on the value of a good packaging system.

At the same time, given that most MacOS users and WIndows users don't use 
packaging systems, and don't have developer tools installed.

For those who do have a packing system (including Linux users), how is the 
package makefile to know if a GiNaC is already installed? And if it isn't what 
to do?

My impression is some significant work is needed to accommodate octave packages 
that depend upon libraries that Octave does not. Perhaps this is another good 
project for GSoC?
