When tor starts it tells me:
[notice] Tor v0.2.4.22 (git-2ee56e4c2c841a45) running on Linux with Libevent 2.0.21-stable and OpenSSL 1.0.2d.
[notice] We were compiled with headers from version 2.0.10-stable of Libevent, but we're using a Libevent library that says it's version 2.0.21-stable.
[warn] OpenSSL version from headers does not match the version we're running with. If you get weird crashes, that might be why. (Compiled with 100000bf: OpenSSL 1.0.0k 5 Feb 2013; running with 1000204f: OpenSSL 1.0.2d 9 Jul 2015).
Any ideas how to solve?
