Migrate eap2 to radius 1.1.6

Hi freeradius members, I would like to include the experimental version such as eap psk and eap sake into my radius 1.1.6. I read the freeradius website, we required to use freeradius 2.0 or later for eap2. So is there any way to migrate eap2 to my current freeradius 1.1.6? Best regards, Thierry
