Modprobe zaptel error

Hi,

Am running Mandrake 10.1 official. Have been able to compile zaptel, libpri and asterisk. After editing the conf files I try to run modprobe zaptel and keep getting the fatal error Module not found. I have tryied running the modprobe command from a number of different directories with no success. Have confirmed zaptel.o and zaptel.ko are in directory.

Ideas?
