Undefined symbol "cbtls_password"

Hello!

I'm installing Freeradius1.1.1 on a FreeBSD 4.11-RELEASE-p8 (from the
ports system).

I'm installing EAP/TLS support (with a mysql backend).

The basic setup (and mysql) works fine. The EAP/TLS part it's the one
witrh the problem that i have.

I'd put the certs on their location, change the eap.conf to reflect
this locations and try to start the server.

I would thank any help that you can give to me so i can see where the
problem lives ;)

I'd tried making a pasword-less and a password-protected certificate
for the server, but anyway the "cbtls_password" came on.

I'm reading about and think that maybe the OpenSSL (OpenSSL 0.9.7d 17
Mar 2004) installation was getting the conflicts, but i reinstalled
(both, the OpenSSL and Freeradius) and the problem persists.

Again, thanks a lot guys!
