Hello Yann,
Thanks for the reply.

Following is the output of *ldd mod_ssl.so, * still the same. No sign of 

OpenSSL library.

root@xxx:/etc/apache2/modules# ldd mod_ssl.so
linux-vdso.so.1 =>  (0x00007fffce1c5000)

libssl.so.1.0.0 => /lib/x86_64-linux-gnu/libssl.so.1.0.0 

Isn't libssl what you are looking for? ([1])

    httpd itself needs no link to openssl, mod_ssl does though.
    So you should have a look at:
    # ldd /etc/apache2/modules/mod_ssl.so
