It's free software, and that kind of is the point of Open Source.

They have stated they are going to remain API compatible with 1.0.1h (or g, forget which they forked) - their new stuff is outside of libcrypto.

It does work today, I am just bit worried that it will keep on breaking with libressl as they evolve their API. I would personally like to avoid more ifdef hell if possible...

Standard way to fix it (on the LibreSSL page) is to check for LIBRESSL_VERSION_NUMBER - e.g. the patch attached which I think catches them all where needed. Note the word think.
It certainly appears to be working anyway with it.

After doing some testing by myself, I noticed that libressl, for some unknown reason, defines
#define OPENSSL_VERSION_NUMBER 0x20000000L
No idea why they decided to advertise that they are OpenSSL v2.0.0. A local fix, if you need one, is to use
#if OPENSSL_VERSION_NUMBER == 0x20000000L #define OPENSSL_VERSION_NUMBER 0x1000100L #endif
in dcrypt-openssl.c after includes.

Hi!
Those are used if
#if OPENSSL_VERSION_NUMBER >= 0x10100000L
So (your) libressl is providing this define. We compile our code using GCC and CLANG regularly, with OpenSSL v1.0.x which is the currently officially supported one.

dovecot 2.2.26.0 uses the following functions, which are not available on libressl 2.4.3:
HMAC_CTX_new HMAC_CTX_free EVP_PKEY_get0_EC_KEY EVP_PKEY_get0_RSA OBJ_length EVP_MD_CTX_new EVP_MD_CTX_free
The result of calling a non-existent function is a runtime error, and we do not want that on production servers.
There are additional problems. I recommend compiling with clang-llvm 3.9.0 to see them all.

OpenSSL v1.0.1 is enough.
