There is something wrong with your manual installation of OpenSSL  
1.0.0e on your machine.  The linker finds your old library instead of  
the new one.  Make sure the library files are properly installed in / 
usr/local/ssl/lib.  You could also rename the old library files for  
the time of building stunnel.
