True. A patch is needed to build against 3.15.x.  I have successfully 
built and am running a patched version of 8.038.00 with 3.15.1.  The 
patch is a bit of a hack from Gentoo post or bug report (I forget which 
at the moment).  It basically puts back an unexpanded version of the 
PREPARED_DELAYED_WORK macro into the code.  The macro was removed in 
3.15, but the underlying structure remains the same. Hopefully a proper 
fix will come out soon.
