-### OpenSSL
-
-OpenBSD uses a replacement of OpenSSL: LibreSSL. This can cause compatibility issues, hence `./configure` will bark if you try to compile with this library:
-
-    Detected LibreSSL: This is NOT supported, and may break consensus compatibility!
-
-To install a 'real' OpenSSL use:
-
-    pkg_add openssl
-   
-Any program linked against this library can only be used after setting the dynamic library path:
-    
-    export LD_LIBRARY_PATH="/usr/local/lib/eopenssl"
-
-(otherwise there will be an error about not being able to find `libcrypto.so.1.0`)
-
-Alternatively, pass `--with-libressl` to `./configure`, however as the warning says, this is NOT supported, and may cause problems syncing the chain, or the node to fork off the network in unexpected circumstances.

 ### Building BerkeleyDB
 
 BerkeleyDB is only necessary for the wallet functionality. To skip this, pass `--disable-wallet` to `./configure`.
