Comment (by engrish):

 I compiled openssl and Tor with following command on CentOS 6.6
 2.6.32-431.el6.x86_64
 {{{
 cd ./openssl-1.0.2
 ./Configure shared enable-ec_nistp_64_gcc_128 linux-x86_64

 cd ./tor-0.2.6.2-alpha
 ./configure --with-openssl-dir=/usr/local/ssl --with-zlib-dir=/lib --with-
 libevent-dir=/usr/local/lib
 }}}
 after a while, I got a warn log when runninng relay
 {{{
 Jan 29 12:09:51.828 [notice] Tor v0.2.6.2-alpha running on Linux with
 Libevent 2.0.22-stable, OpenSSL 1.0.2 and Zlib 1.2
 .8.
 ...
 Jan 29 12:11:02.000 [warn] Invalid result from curve25519 handshake: 4
 Jan 29 12:11:02.000 [warn] onion_skin_client_handshake failed.

 Jan 29 12:11:02.000 [warn] connection_edge_process_relay_cell (at origin)
 failed.
 }}}
 In my case, this problem solved with zlib.
 {{{
 cd ./openssl-1.0.2
 ./Configure shared zlib enable-ec_nistp_64_gcc_128 linux-x86_64
 }}}
