I noticed that selinux_sepgsql_context_path(3) was also got merged at libselinux-2.0.83. So, we could check correctness of library versions using existence of this function. Does this patch expectedly abort the configure script on older libselinux installation? I'm not available to setup Ubuntu environment immediately.
