I'm happy to help. But I'm not Debian packaging expert. Can you provide
some information how to build and test the packages locally (preferably add
that information to http://llvm.org/apt/)?

It should be included now.

Pablo wrote some great documentation on how to build the packages:
http://llvm.org/apt/building-pkgs.html

Cheers,

Sorry to inform about that but the packages are in worse condition than
before:

   1. Firstly, the cmake shared files have been moved from
   /usr/share/llvm/cmake to /usr/lib/llvm-3.8/share/llvm/cmake. The previous
   location was searched by cmake by default so cmake was able to find LLVM
   package without any additional help.
   2. The cmake shared files refers at least one non-existing/not-installed
   libraries:

    CMake Error at
/usr/lib/llvm-3.8/share/llvm/cmake/LLVMExports.cmake:1034 (message):
      The imported target "PollyISL" references the file

         "/usr/lib/llvm-3.8/lib/libPollyISL.a"

      but this file does not exist.  Possible reasons include:

      * The file was deleted, renamed, or moved to another location.

      * An install or uninstall procedure did not complete successfully.

      * The installation package was faulty and contained

         "/usr/lib/llvm-3.8/share/llvm/cmake/LLVMExports.cmake"

      but not all the files it references.

    Call Stack (most recent call first):
      /usr/lib/llvm-3.8/share/llvm/cmake/LLVMConfig.cmake:173 (include)
      CMakeLists.txt:30 (find_package)
