with problems reported earlier, no failure. With 39062 on my usual login but after a thorough make distclean and control over errant R_LIBS, no failure. This morning with make distclean and updates to methods - svn 39076, no failure. So I think the failures were probably provoked by stale software components as Brian Ripley suggested, rather than by unresolved methods package issues as such. Happily, rgdal (depends on sp) also passed check at R 39076.
