Hi,

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

Relevant part:

The full build log is available from:
   http://people.debian.org/~lucas/logs/2009/12/10/llvm-gcc-4.2_2.6-3_lsid64.buildlog

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.
