Have had a lot of problems trying to get a recipe running.
I finally discovered that "COMPATIBLE_MACHINE" is sensitive to whitespace.

Working:
COMPATIBLE_MACHINE = "machine1"
COMPATIBLE_MACHINE = "machine1|machine2"
COMPATIBLE_MACHINE = "(machine1)"
COMPATIBLE_MACHINE = "(machine1|machine2)"

COMPATIBLE_MACHINE = "machine1"
COMPATIBLE_MACHINE += "|machine2"

Not Working:
COMPATIBLE_MACHINE = " machine1"
COMPATIBLE_MACHINE = "machine1 "
COMPATIBLE_MACHINE = "machine1|machine2"
COMPATIBLE_MACHINE = "machine1 |machine2"
COMPATIBLE_MACHINE = "machine1| machine2"
COMPATIBLE_MACHINE = "machine1 | machine2"
COMPATIBLE_MACHINE = " (machine1)"
COMPATIBLE_MACHINE = "(machine1|machine2) "
etc.

This is a real PITA expecially since COMPATIBLE_MACHINE is yet to be 
documented in the manual
