I see a breakage of Emacs build on master under MacOS 10.13. Build stops with the following message:

org/org-timer.el:39:1:Error: Searching for program: Is a directory, /bin/zsh

The file in question is not a directory:

% ls -l /bin/zsh

404K -rwxr-xr-x 1 root wheel 596K

Yes, it is. I can't find the relevant sources right away, but opening a file inside a file is a syntax for opening resource forks under OS X, so `/foo/bar/baz/.` is a "directory" of resource forks there. This syntax is not likely to go away anytime soon.
