Hi, I just tried building python-oauth2client, and it worked without any problem. I tried in a plain sid, and another time with sbuild in a clean chroot.
Could you please give details on how you rebuilt, because I can't reproduce it. For example, the things you're using to do reproducible built, etc. I'm downgrading this bug severity therefore, until I know further. Hopefully, we'll find out what's going on. Cheers, Thomas Goirand (zigo)
