I get warnings about the following undeclared functions when building dev-libs/apr-util-1.6.1:
These functions are deprecated in OpenSSL 1.1.0, and no longer declared without some compatibility layer enabled. Moreover, the OpenSSL 1.1.0 .so does *not* provide them.
So even if these are mere warnings, the resulting .so will fail to load when used.
To see this for yourself (needs =dev-libs/apr-util-1.6.1 built against =dev-libs/openssl-1.1.0g obviously, and installed):
> import os
> import ctypes
> lib = ctypes.CDLL('/usr/lib64/libaprutil-1.so.0.6.1', mode=os.RTLD_GLOBAL)
# above load is required as the apr-util crypto lib is meant to plug into it
> libcrypto = ctypes.CDLL('/usr/lib64/apr-util-1/apr_crypto_openssl.so')
# fails with error: undefined symbol ENGINE_cleanup

Patch that removes the unneeded, deprecated function calls. Note I only checked that the library loads fine afterwards (using above Python/ctypes technique).
This has been submitted upstream .
https://github.com/apache/apr is a mirror and you are unlikely to get any answer there. See: https://apr.apache.org/patches.html
I think you shouldn't use "APR_USE_OPENSSL_PRE_1_1_API". Use something like
> #if (OPENSSL_VERSION_NUMBER < 0x10100000L) || defined(LIBRESSL_VERSION_NUMBER)

Since we decided to no longer build openssl without deprecated features, this
bug can now be considered as fixed (but will eventually reappear once openssl
upstream finally removed deprecated features from their code).
