Does it work with bootstrap-mk-files-20080415?
Yep - that seems to have fixed it!(Incidentally, should some protection be put upon bootstrap-mk-files? If you try to update it, the build process first removes the files, and then bmake fails (due to these files missing) before it can re- install them. Manually copying the files fixes this - but this is messy. I seem to remember that some package (pkg_install itself?) is marked as not to be uninstalled - could the same be added to bmake and its dependencies?)
