有谁在LFS7.0成功编译Linux-PAM和quota-4.0的

moonligh

编译quota出现undefined reference to ‘xdr_u_int’
undefined reference to `xdr_string'
undefined reference to`xdr_int'  
undefined reference to`xdr_enum'
undefined reference to`clnt_create'
undefined reference to`authunix_create_default'

编译Linux-PAM出现undefined reference to clnt_create
undefined reference to `authunix_create_default
undefined reference to xdr_string
undefined reference to xdr_int

请问是少了什么链接库
