"Guile authentication disabled in config" after upgrade to 1.6.1

Hello,

I just upgraded to 1.6.1 from 1.3 and I'm getting this message now:

Aug 18 09:02:20 [32724]: Acct.error: (Accounting-Request x.x.x.x 60 "username" 
CLID=async CSID=xxxxxxxxxx): Guile authentication disabled in config


I copied the new dictionaries in, but the rest of the files are from my radius 
1.3 install (and probably from before that even).


Any assistance would be appreciated.

Thanks,

Dale
