I've a CURRENT r281990 that won't complete buildworld, nor installworld from

 an obj rsynced from r285019. 
 and a src r285239
 IOW former won't install
 latter won't build...

 ( missing files, etc... error varies)

 Just a slight chance anyone has run into a similar situation...

 Current error is in /usr/src/lib/clang/libllvmsupport (file not found) 
 during buildworld



 elsewhere, 
 "don't know how to make auto.obj.mk"
 (usr/src/contrib/llvm/include) "make install" -- the above error occurs

 I don't suspect a mismatch between src and obj (former not building, latter already
 built); only a few days apart as to upgrades. 



 Hopefully stated clearly enough. 
 Not that important now, but may eventually be a showstopper.

 I've checked "man build" and UPDATING and not really sure how to proceed.
