I end up without a complete nextstep/Emacs.app most of the time, and it seems to be a problem with directories not being created before one of the workers wants to use it. Three questions: 1.) Is the ns-app code known to be unable to use parallel compilation? 2.) Does it matter that I do full rebuilds each time, starting with autogen.sh and ending with make bootstrap install)? 3.) Can anyone suggest a good way to start debugging this? Thanks, *Chad
