libssl.so.6 not found for check_nrpe

I couldn't get NRPE to work, so I ran it locally and this error popped up: ./check_nrpe: error while loading shared libraries: libssl.so.6: cannot open shared object file: No such file or directory After I check my "check_nrpe" with ldd command, I got this : [root@supervision lib64]# ldd /srv/eyesofnetwork/nagios-3.5.1/plugins/check_nrpe linux-gate.so.1 => (0xf7744000) libssl.so.6 => not found libcrypto.so.6 => not found libnsl.so.1 => /lib/libnsl.so.1 (0xf7720000) libc.so.6 => /lib/libc.so.6 (0xf7562000) /lib/ld-linux.so.2 (0xf7745000) But I'm providing libssl and libcrypto for "6".
