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/2011/09/23/qutemol_0.4.1~cvs20081111-1_lsid64.buildlog

This happened because since dpkg 1.16.0 [0], hardening flags are enabled 
under various conditions.

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.
