Updatin OpenSSL to 0.9.8zh

Hello,

since one client runs ElCapitan (10.11.2) this client has problems with cardDAV, calDAV and sometimes also with smtp.

Someone suggested there might be a problem with the installed version of openSSL on the server, so I thought, why not updating it from 0.9.8y -> 0.9.8zh, which is the same version on 10.11.

Anybody did that already?

Are these options working fine:

sudo ./configure --prefix=/usr/ darwin64-x86_64-cc shared

or is there something missing/better?

The box is running Apache, Mailman, Postfix with Spamassasin etc and 4D13 (that's why I currently can't update to ServerOS5.x).

Thanks
