Loading module error


#1

Can someone plz tell me how to fix this problem. When i run asterisk, it gives me the following error:
Warning[7463]: loader.c: 313 load_resource: /usr/lib/asterisk/modules/pbx_wilcalu.sc: undefined symbol: ast_pthread_create

Warning[7463]: loader.c: 523 load_modules: loading module pbx_wilcalu.so failed

How do i fix this problem. I just need to configure asterisk so i can use a sip soft phone to make a call to msn messenger.
