[root@150 keepalived-1.2.13]# ldconfig -p|grep ssl
        libssl3.so (libc6,x86-64) => /usr/lib64/libssl3.so
        libssl.so.10 (libc6,x86-64) => /usr/lib64/libssl.so.10
        libssl.so (libc6,x86-64) => /usr/lib64/libssl.so
[root@150 keepalived-1.2.13]# ldconfig -p|grep popt
        libpopt.so.0 (libc6,x86-64) => /lib64/libpopt.so.0

[root@150 keepalived-1.2.13]# rpm -qf /lib64/libpopt.so.0
popt-1.13-7.el6.x86_64
[root@150 keepalived-1.2.13]# rpm -qf /usr/lib64/libssl.so
