New PARI spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/pari-2.4.3.svn-12577.p3.spkg
New genus2reduction spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/genus2reduction-0.3.p8.spkg
New lcalc spkg: http://sage.math.washington.edu/home/jdemeyer/spkg/lcalc-20100428-1.23.p2.spkg
Patch for data/extcode: extcode_9343_combined3.patch
Patch for sage/devel: sagelib_9343_combined7.patch

The above list also indicates the order in which to install the spkg's and patches. In particular, the genus2reduction spkg will not install without the new pari spkg.

For reviewers

Download sage-4.6.prealpha1.tar, which is a complete Sage distribution based on sage-4.5.3.alpha1. Just extract it, and type make. In this file, the following tickets have been merged:
- 9343 (needs_work): PARI upgrade
- 9591 (needs_review): genus2reduction
- 9592 (needs_review): lcalc
- 9750 (positive_review): Document that PARI no longer assumes more than GRH
- 9636 (needs_review): Catch output from PARI in Sage
The main issue seems to be making sure it actually compiles.
For reference, these are the patches for the spkg's:
- pari
- genus2reduction (note that old genus2reduction.c file was not under revision control unfortunately)
- lcalc

Debugging PARI/GP build errors

If the new pari spkg doesn't build, you should try building PARI/GP stand-alone (i.e. outside of Sage). You should download pari-2.4.3.svn-12577.p3.spkg and then type the following in a shell:

tar xjf pari-2.4.3.svn-12577.p3.spkg
cd pari-2.4.3.svn-12577.p3/src
./Configure --graphic=none
make gp

If this works, this is a bug in Sage's build process for PARI/GP. If this gives errors, this indicates an upstream issue with PARI/GP. In any case, any errors should be reported on the Sage trac.
