EZProxy ssl security

So I just ran my EZproxy through an SSL checker and was shocked by the 
outcome:

https://www.ssllabs.com/ssltest/analyze.html?d=login.helicon.vuw.ac.nz

Finding other EZproxy installs in google and checking them gave a range 
of answers, some MUCH better, some MUCH worse. Clearly secure EZproxy is 
possible, but patchy.

Is there a decent guide to securing EZproxy anywhere?

I'm hoping that it might be as simple as dropping a new openssl library 
into a directory within the EZproxy install?

cheers
