Hi,
One thing I don't understand...if you're trying to build with the engine
version, there are problems with the header files that you should have
run into already.  Did you disable stunells' default no-dh?  If not, I
think that the header files that it's finding are not those of an engine
version of OpenSSL.
The problem you're seeing is that the engine version of OSSL uses the
various dl functions to open the third party shared libraries used below
the engines. Your stunnel is not linking with -ldl. Did you build
OpenSSL yourself? If so, did you build with the -shared option to build
the shared libraries?  Did you tell stunnel where to look for your
freshly built OpenSSL via --with-ssl?
I'm building OpenSSL shared objects and when I build an tunnel with
--with-ssl pointed to it, it links automatically with -ldl.  
A quick fix is to stick a -ldl in your makefile........
