Yes, this is because of the bad advice to run "make delete-old" before you had run "make installworld". You had an older version of libc++ in /usr/include/c++, but that still required the __undef___deallocate header, which has now been deleted by "make delete-old". Your best chance is to build and install libc++ first, if possible, by doing: cd /usr/src/lib/libc++ make obj make depend make make install Then retry building world. -Dimitry
