[oe] tk 8.6.0: strange error: "oe_runmake: command not found"

[Nick D'Ademo]

I'm encountering a strange error at the install step with the tk 8.6.0
recipe (full log below). Does anyone have any ideas on this?
This recipe was compiling fine before (and has not been recently changed -
last change Dec 5 2013) so I'm not sure what has broken it...

Thanks,
Nick
