Packages need rebuild for libopenthreads6 -> libopenthreads7 and libopenscenegraph6 -> libopenscenegraph7 transitions.

Be aware that osgcal currently FTBFS on i386: https://launchpad.net/ubuntu/+source/osgcal/0.1.46-2.1/+build/678616

It doesn't on all other arches since the test which fails is skipped, so, its either the test which is wrong or the package really doesn't work.

I don't have upload the debdiffs yesterday because the packages have not finished to build on my PPA.

Here the debdiff for openscenegraph source package

For osgcal I have search in the build log and found this error:
"(EE) AIGLX error: dlopen of /usr/lib/dri/swrast_dri.so failed (/usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory)"
I have also found that this file is provided by the libgl1-mesa-dri package.

Trying both depends and rdepends on apt-cache I have found (among with the help of ~d.filoni) the possible cause of the problem:
# apt-cache depends libgl1-mesa-glx
libgl1-mesa-glx
  <...>
  Conflicts: libgl1-mesa-dri
  Replaces: <libgl1>
    libgl1-mesa-glx
    libgl1-mesa-swx11
  Replaces: libgl1-mesa-dri

So I have tried adding the libgl1-mesa-dri package as build-dep in debian/control and the package was successfully built on my PPA:
https://launchpad.net/~volans/+archive/+build/704939

I attach here the debdiff

Its not very clear to me why you want to rebuild openscenegraph:
libopenthreads7 and libopenscenegraph7 are both binary packages of openscenegraph ?
If you are talking about the NBS list (http://people.ubuntu.com/~ubuntu-archive/NBS/) then only osgcal needs to be rebuilt (if the FTBFS is solved).

You are right, I have been mislead by the libopenscenegraph6 NBS (http://people.ubuntu.com/~ubuntu-archive/NBS/libopenthreads6) that involve both osgcal and libopenscenegraph6 packages and forgetting that libopenscenegraph6 will be superseded by libopenscenegraph7. Sorry, I close the openscenegraph task as invalid.
For osgcal and the FTBFS I have linked the successful build on my PPA in my previous reply.

This bug was fixed in the package osgcal - 0.1.46-2.1ubuntu1

---------------
osgcal (0.1.46-2.1ubuntu1) intrepid; urgency=low

  * Rebuild against OpenSceneGraph-2.4 (LP: #263122)
  * debian/control: add libgl1-mesa-dri as build-dep, fix FTBFS on i386
