Hi Jörg, I've seen that you have added the patch from Yue to the git repository and dropped d/clean again, which I used for the NMU.
Yua's patch has one problem: It will still look for the local as fallback libzip.a, and you *MUST NOT* use that one, even on amd64. The best thing to ensure that would be not to ship libzip.a in the first place, the second best thing would be to delete the file to ensure that it is not accidentially used. Cheers, -- tobi
