 This is a fundamental infrastructure problem (inherent in the way make
 update works) and not fixed, nor easily fixed.
 
 The workaround is to find the package(s) where a subordinate make
 update was launched, and restart make update in each of them, the most
 recent first. You can find these packages by the existence of
 work/.DDIR or work/.DLIST files. Do *not* make clean; that will throw
 away the list of packages to rebuild.
 
 In general make update is not really recommended because it can tie
 itself into various knots (this being one of them);
 pkg-rolling_replace is usually a better method.
