My issue was nothing more complex than having downloaded the full dahdi
package. The result is it unpacks to:

/usr/src/dahdi/linux/drivers/staging -
not /usr/src/dahdi/drivers/staging.

Fix was nothing more simple than moving the contents
of /usr/src/dahdi/linux/ to /usr/src/dahdi/ and the 'howto' worked
pretty much like a charm :-)
