problem building virtualbox-ose-kmod

having this issue building virtualbox-ose-kmod, its been like this for a 
while but I deinstalled and forgot, for quite a while now, maybe over a 
month. now that I've moved from 13-current to stable/13 I thought I 
would try to put it back, but it still wont build. I haven't seen anyone 
else with this problem, did I miss a memo?
