CHANGES:

1. I changed M2/Macualay2/packages/Makefile.in to have the following
near the top.  This speeds up the build a lot and lets it complete
on OS X intel where there is a problem with two examples.

RemakeAllDocumentation ?= false
#IgnoreExampleErrors ?= false
IgnoreExampleErrors ?= true
#CheckDocumentation ?= true
CheckDocumentation ?= false

-----------------

UPDATING:
To get the newest Macaulay2 source and package it for including
in SAGE do the following:

 mkdir -p tmp
 cd tmp
 svn export svn://u123.math.uiuc.edu/macaulay2/trunk/M2
 make -C M2 -f Makefile

Then

 cd ..
 rm -rf M2
 mv tmp/M2 .
 rm -rf tmp
