Old description:
New description:
As of Sage 7.3.beta6, building Sage requires a system Python >= 2.7
because `sage-uncompress-spkg` uses `argparse`.
While we already ship a copy of `argparse.py`, `sage-uncompress-spkg`
currently doesn't try to import it from where it's located in the Sage
tree.

Comment:
Replying to [comment:16 embray]:
> If it's too much trouble, I can also just change this script to use
`optparse` instead of `argparse`. I don't think there's really any
`argparse`-specific features that it's strongly relying on.
I rather meant to ask whether it's only the above little change we need,
but I've meanwhile built Sage 7.3.beta6 from scratch with that on a system
with just Python 2.6, which worked without any issues. (`argparse.py`
already gets shipped in `build/sage_bootstrap/compat/` anyway.)
So now the question is whether I should put a branch ''here'' or open a
separate ticket specifically for `sage-uncompress-spkg` as the ticket's
title sounds pretty generic (as if it was meant to be a meta-ticket).
