Please can someone help I'm new on the list

I'm trying to install Radius EAP/TLS but when I enable the EAP module, I get the following Error: rlm_eap: Failed to link EAP-Type/tls: rlm_eap_tls.so: cannot open shared object file: No such file or directory radiusd.conf[10]: eap: Module instantiation failed. radiusd.conf[1960] Unknown module "eap". radiusd.conf[1907] Failed to parse authenticate section. Can someone help me. Thanks
