Module Errors

I'm trying to compile a module via the following:

cc -D__KERNEL__ -D__KERNEL_MODULE_sparc=1 
-I/usr/src/linux-2.4.20-2.3sparc/include -Wall -Wstrict-prototypes 
-Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing 
-fno-common -Wno-unused -pipe -m32 -mtune=ultrasparc -DMODULE 
-DMODVERSIONS -include 
/usr/src/linux-2.4.20-2.3sparc/include/linux/modversions.h 
-DKBUILD_BASENAME=ppp_generic -DEXPORT_SYMTAB -c ppp_generic.c


I receive no errors, yet when I run depmod -a later I get:

Updating module dependencies
depmod: ELF file 
/lib/modules/2.4.20-2.3sparc/kernel/drivers/net/ppp_generic.o not for 
this architecture


Any ideas on what I should be looking at to fix this?

Any help appreciated.
