It's a known issue due to the use of the CTS mode API that is only
present in OpenSSL >=1.0:

  http://krbdev.mit.edu/rt/Ticket/Display.html?id=6747&user=guest&pass=guest

It should be possible to implement CTS mode on top of the CBC mode of
OpenSSL 0.9.8.  We would be happy to consider a patch.  There may be
other dependencies on OpenSSL >=1.0 but that is the main one that I am
aware of.
