In order to get version information (required by shell): objdump -x libntl.so
check symbolic links, for example in my local install (Ubuntu 14.04, sage-6.9) I have in the sage-src/sage-6.9/local/lib directory two links: libntl.so and libntl.so.16 pointed to the dynamic library file libntl.so.16.0.0 restart your operating system to unload the dynamic libraries (Note: I don't know how to restart a "docker container") Dominique -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
