2.6-test4: mpspec.h:6:25: mach_mpspec.h: Missing file

[j d]

Hi. 
I'm trying to build a (add-on) module 
on a machine booted from a 2.6-test4 kernel,
And keep running into this error. I've 
included a sample program , and gcc command
line.

I built the kernel:

make defconfig; 

It is a 2W SMP (Compaq ML850)
couple minor modes like enet & SCSI device
make
My general question is, should I include the 

-I/work/src/<build>/include/asm-i386/mach-generic/mach_mpspec.h

in my gcc command line or is my build area incorrect
is
some way that the correct mpspec.h file can't be found
?

Thx. JD.
