Generally (depending on the version of stunnel) it shouldn't work, as  
some API functions only available in a new versions of the OpenSSL  
library will not be exported by an old library.  Even if you're able  
to start stunnel, runtime problems are expected.

If your problem is that you can't upgrade your OS - there is a simple  
workaround.  Just replace:
	/your_dir/bin/stunnel /your_dir/etc/stunnel/stunnel.conf
	LD_LIBRARY_PATH=/your_dir/lib/ /your_dir/bin/stunnel /your_dir/etc/ 
where /your_dir/lib/ is where your OpenSSL 1.0.1 shared libraries are
