Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

The full build log is available from:
   http://people.debian.org/~lucas/logs/2011/09/23/g2_0.72-2_lsid64.buildlog

This is probably due to special hand-fiddling with debian/patches/* 
quilt series. With dpkg >= 1.16.0, "When dpkg-source automatically applies
patches at the start of the build process, it will also automatically unapply
them at the end of a successful build." [0]

About the archive rebuild: The rebuild was done on about 50 AMD64 nodes
of the Grid'5000 platform, using a clean chroot.  Internet was not
accessible from the build systems.
