Upgrade to pynac-0.7.3

[rwst]

Main addition is Gosper summation (see Sage #22090 for details).

https://github.com/pynac/pynac/releases/download/pynac-0.7.3/pynac-0.7.3.tar.bz2

Changed to critical because of an included fix to the broken Pynac/Singular interface.

No Python code or doctest changes with this version. The Gosper sum interface is handled in #22090.

LGTM. Off to the build bots.

If you think that needs to be in 7.5 it should be made a blocker, otherwise I am afraid it will be 7.6 material at this stage.

Right. A blocker it's not.

Replying to @kiwifb:

Cannot confirm. You probably built Pynac without "--with-giac=no". The broken giac support is fixed in pynac git. See also pynac/pynac#223

comment:11

My dev machine seems to be down, I have now read the github issue and like them I enabled giac support so thats probably it. I'll include that commit in sage-on-gentoo at the first opportunity. Since I am taking proper holidays with my familly we may be looking at the 16th of January if I don't get access to my box by tomorrow.

This fails to build for me on OS X. I'm attaching the log file from a serial build.

No, it's too big to attach. It's here: http://www.math.washington.edu/~palmieri/Sage/pynac-0.7.3.log

See #22147 for the follow up on OS X.
