recently some autobuilds of netbsd-4 failed with the error:

   libasn1/Makefile contains:
   
   LIBDPLIBS=      com_err ${.CURDIR}/../libcom_err
   
   lib/Makefile has:
   
   SUBDIR+= .WAIT libroken libvers libcom_err libasn1
   
   shouldn't there be some ordering constraint between libasn1 and
   libcom_err? Should I add .WAIT between them?
   

ah, i fixed this in -current.  see lib/Makefile 1.114.
