Looks like there’s a little problem with Mac OS 10.14 beta:
appears to think executables aren’t, so it removes the executable bit after
==> Cleaning Fixing /usr/local/Cellar/fakeroot/1.22/bin/faked permissions from 755 to 444
So far this has affected only a small number of packages for me, e.g.
fakeroot, p7zip, xz and doxygen, but seems like it’d be a wider problem.
If it affects you, the obvious chmod +x should get you past the problem.
To reproduce, do e.g. ‘brew install fakeroot’ and then try to run fakeroot.
Probably something wrong with mach_o_executable? in os/mac/mach.rb, but coming up the learning curve there is beyond what I can do this afternoon.
