 No, I don't. I never even noticed any of this until I was trying to
 diagnose this particular issue, my (limited) bulk builds always "just
 worked" for me. (I don't use mlterm.)
 
 My basis for defining the sandbox has always been essentially what
 pkgtools/mksandbox does, which doesn't seem to cover this case (and I'm
 guessing that's true for some other installations, or they follow some
 other similar means of definition).
