Do you still see this issue with the current version? We have successful builds of this port on recent macOS versions on our automated build system.

From your log, it looks like it's trying to use local copies of stdlib.h and unistd.h, which is failing because these expect some config.h to be included first.

stdlib.h and unistd.h are standard system headers which are already provided by Xcode or the command line tools and the standard versions do not require the inclusion of any config.h. Presumably emacs includes these headers for compatibility with ancient systems that don't have them however its configure output shows that it has correctly detected that your system has these headers so I don't know why it is still trying to use its own versions.
