Replying to [comment:22 cremona]:
> Bruce and I used readline-6.2.p2.spkg not the p3, and also used it on a
fresh build of 4.7.2 (which had previously stalled building R).
> So the following might not be relevant: after building, when we run Sage
it gives a 2-line warning that readline is not available -- and indeed
Sage has no history functions. What did we do wrong?
Before building Sage (or [re-]installing '''Sage's''' readline), you need
to
{{{
#!sh
$ sudo apt-get install libncurses5-dev libncursesw5-dev
}}}
(The latter depends on the former, so you actually have to specify only
one of them). You '''do not''' have to install any ''libreadline''
package, as Sage builds and uses its own -- the one we're talking about
here.

> Bruce also tells me that although he installed all the ubuntu packages
listed on the installation web page, he also had to install dpkg-dev
before Sage would build.
I'm pretty sure the instructions on the web page are still outdated (and
by the way have been wrong anyway), as discussed with Harald on sage-
release a while ago.
`dpkg-dev` is needed since Ubuntu 11.04, in order to make Python build
(because the locations of some libraries were changed in Debian/Ubuntu).
----
I'm sorry I'm unable to work much on Sage at the moment; thanks John for
providing an updated and rebased spkg of my preliminary one.
