Hi David,
The problem is that Sage patched libcdd and added features that are not
included upstream [1]. The changes are actually not that big. The new
features are in cdd_both_reps.c and the rest should be mostly a switch
of the random number source to something deterministic, I guess to avoid
problems with tests.
If the changes were included upstream there wouldn't be a problem. I saw
that you are mentioned on the libcdd homepage. Do you know Komei Fukuda?
In that case maybe you could try to bring this to his attention? I had
no luck with previous attempts contacting him about a soname policy for
cddlib.
Best,
Tobias
