Hi,
Thank you for the explanation: I kind of guessed that some part of sage were
omitted to adapt the two packaging system but your explanation gave me the
details I was missing. 
As you said the combinat queue is/should be a real mess of continuous
updates (at least this is what I was told) so I am not entirely sure how well
an e-build would perform, in case you decide to spend some time on it I will
gladly be a guinea pig for testing it out.
I do not understand sage package system in details so my request may just be
stupid but is it possible to produce separate ebuilds for the different part 
of sage that are now stripped? If not for all of those can this be done for the
various packages in $SAGE_ROOT/devel ? If an e-build is not feasible, can
USE flags be used to select which extensions to include at compile time?
Thank you
S.
