failure to re-install ipython

[Dima Pasechnik]

in the Sage 9.0.beta2 I get
....

to make it build. In particular the last chunk removed by this patch
looks as something outdated.

Any ideas?

I just saw this problem today, too. I agree that the last chunk looks outdated.

Just curious: what platform is this?
