[Debian-science-sagemath] 62 failed tests and classification of remaining failures

[François Bissey]

In Gentoo (and the test is fine for me):
ldd -r /usr/bin/cdd_both_reps
	linux-vdso.so.1 (0x00007ffe1e1db000)
	libcdd.so.0 => /usr/lib64/libcdd.so.0 (0x00007fe9cb88f000)
	libc.so.6 => /lib64/libc.so.6 (0x00007fe9cb4f3000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fe9cbab0000)
Is your libcdd really different from your libcddgmp?
ldd -r /usr/lib64/libcdd.so
	linux-vdso.so.1 (0x00007ffec3a65000)
	libc.so.6 => /lib64/libc.so.6 (0x00007f2045031000)
	/lib64/ld-linux-x86-64.so.2 (0x0000561003df2000)
