freeradius X error "failed to load module "perl""

[John Estrella]

Hi All,

I have Ubunto 12.04.3 server and installed LinOTP and FreeRadius using the following website instructions.  Not sure the versions of LinOTP and FreeRadius installed but I'm guessing the latest versions since I didn't specify a version during download.
https://thenetworkcable.wordpress.com/2014/11/28/two-factor-authentication-with-linotp-google-authenticator-totp-and-a-juniper-mag/

I followed each step and had no errors setting anything up.  When running "radtest username OTPpassword 127.0.0.1 0 mypass", I receive an error saying "radclient: no response from server for ID 234 socket 3"

Afterwards, I ran freeradius -X debug and got the following message:

Radius: #### Loading Virtual Servers #### server { #from the file /etc/freeradius/radius.conf  modules {
  Module: Creating Auth-Type = perl
 Module: Checking authenticate {...} for more modules to load
/etc/freeradius/sites-enabled/linotp[13]: Failed to load module "perl".
/etc/freeradius/sites-enabled/linotp[12]: Errors parsing authenticate section.

I have searched plenty and haven't found any difinitive solutions.
Your help is greatly appreciated.

John
