Yes, install OpenSSL instead.

OpenSSL installed, but does not solve the problem.

Please post config.log and what version of OpenSSL you are using.

I compile it --with-libressl flag.

The paste is incomplete; what version of OpenSSL is this?
ghost commented at 4:35 AM on July 29, 2015: none

OpenSSL 1.0.1k

The problem here, it appeared, is that OpenBSD, when you use pkg_add openssl installs openssl as the pkg-config package eopenssl:

orion@lethe:~/bitcoin$ pkg-config --libs --cflags openssl  
-I/usr/include -L/usr/lib -lssl -lcrypto
orion@lethe:~/bitcoin$ pkg-config --libs --cflags eopenssl 
-I/usr/local/include -L/usr/local/lib/eopenssl -lssl -lcrypto

But couldn't even work around this with the painful:

./configure ... SSL_CFLAGS="$(pkg-config --cflags eopenssl)" SSL_LIBS="$(pkg-config --libs eopenssl)" CRYPTO_CFLAGS="$(pkg-config --cflags eopenssl)" CRYPTO_LIBS="$(pkg-config --libs eopenssl)"

config.log shows:

configure:26667: checking for a supported OpenSSL version
configure:26682: eg++ -o conftest -g -O2 -Wall -Wextra -Wformat -Wformat-security -Wno-unused-parameter  -Wstack-protector -fstack-protector-all -fPIE  -DHAVE_BUILD_INFO -D__STDC_FORMAT_MACROS  -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2   -Wl,-z,relro -Wl,-z,now -pie conftest.cpp  -L/usr/local/lib/eopenssl -lssl -lcrypto -L/usr/local/lib/eopenssl -lssl -lcrypto >&5
conftest.cpp: In function 'int main()':
conftest.cpp:68:14: error: 'RAND_egd' was not declared in this scope
 RAND_egd(NULL);
              ^

Multiple problems here, which I could eventually work around:

The libressl check ignores SSL_CFLAGS/CRYPTO_CFLAGS: fixed in #6729
pkg-config --cflags eopenssl returns -I/usr/local/include, should be -I/usr/local/include/eopenssl (upstream issue)

After applying #6729, explicitly specifying the locations works:

./configure ... SSL_CFLAGS="-I/usr/local/include/eopenssl" SSL_LIBS="-L/usr/local/lib/eopenssl -lssl" CRYPTO_CFLAGS="-I/usr/local/include/eopenssl" CRYPTO_LIBS="-L/usr/local/lib/eopenssl -lcrypto"

I can forgive you for eventually going with --with-libressl flag.

Edit: Happy we can drop the libressl check after switching to secp256k1 verification...

Edit.2: this fixes compiling; for running e.g. the tests you need export LD_LIBRARY_PATH="/usr/local/lib/eopenssl"
