Trying to upgrade to latest (2.31.17) from 2.29.00, i386, and am getting this error:
server/fop2_server: symbol lookup error: /tmp/par-726f6f74/cache-42500eee0cc6d9b9f21916d9c1dace54f3fc476d/libssl.so.6: undefined symbol: CRYPTO_memcmp

I've already updated the licence (annual maintenance).

What am I missing?

SHMZ (CentOS) release 6.5 (Final)
FreePBX Distro 5.211.65-21

2.6.32-431.el6.i686 #1 SMP Fri Nov 22 00:26:36 UTC 2013 i686 i686 i386 GNU/Linux

Solved. I hope no one else has this issue. Good luck if you do.
