Error building pyprocessing on Solaris SPARC after changes to python

[sagetrac-drkirkby]

== The computer hardware & software ==

• Sun Blade 1000
• 2 x 900 MHz UltraSPARC III+ CPUs
• 2 GB RAM
• Solaris 10 03/2005 - the first release of Solaris 10.

== The Sage software ==
Sage 4.3.3 which comes with python-2.6.4.p5 and pyprocessing-0.52.p0

== The problem ==
This is a long story, so I'll keep it short.

• Implement 2-isogeny descent over QQ natively in Sage using ratpoints #6583 "Implement 2-isogeny descent over QQ natively in Sage using ratpoints" was integrated into Sage 4.3.1.

• The above patch, which was not properly checked on Solaris, broke the Solaris build as reported at GCC reports incorrect flags compiling descent_two_isogeny.c on Solaris 10 #7867

• Jaap Spies found this link http://bugs.python.org/issue1759169 which suggests this is a bug in python, which will be fixed in the next 2.6 release. But a patch is provided on the python web site.

• remove the pyprocessing spkg from sage, then sort out any fallout that results #6503 is an 8-month old patch to remove pyprocessing from Sage, as the multiprocessing module, which has a slightly different API, is now part of Python 2.6.

• The patch at http://bugs.python.org/issue1759169 was integrated into python-2.6.4.p5, but it broke the build of pyprocessing as below

The revised spkg can be found at:

The Mercurial patch is attached.

Updating to blocker, as this essential for a succesful Solaris build. However, if #6503 is merged, then this can be ignored, as that intends removing all of pyprocessing. But the ticket is 8 months old.

Closing this as wontfix since #6503 removes pyprocessing from the standard spkg repository.
