[stunnel-users] FIPS_mode_set error

[th at ftlabs.com]

I just installed Stunnel-4.27 on a Linux box and cannot get it to  
start with a test config that works on another box running same  
version of Stunnel.  I get the following output...

[root at dvl stunnel]# stunnel stunnel.conf-test

Does anybody have a clue what may be causing this and how to fix it?   
Please pardon my ignorance regarding OpenSSL.
