A test rebuild of raring ringtail started in 2012 for the amd64, i386 and armhf architectures is now finished for all components on armhf. The amd64 and i386 rebuilds will hopefully finish in a few days.
Results can be seen at http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-2012122...
The archive for the test rebuild is https://launchpad.net/ubuntu/+archive/test-rebuild-20121221/
Some common build failures are:
- not finding pyconfig.h, installed into a multiarch include dir - eglibc-2.16 changes (puts).
Please help fixing the build failures for the final release.

PS: For those interested, a second test rebuild using a snapshot of GCC-4.8 is going on. Status at http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-2012122...
