Hi,
During a rebuild of all packages in sid, your package failed to build on amd64.
It lloks like you are a debian developer and have interest in 3D-animation. I want to ask, if you are able to update the white_dune package in debian. The current version 1,874 has many improvements compared with the 7 years old version 0.30 im debian... I am the upstream of white_dune... https://wdune.ourproject.org/ white_dune can be used to create content for the castle-game-engine. so long MUFTI
