osx - Why is /usr/bin/arch not installed? -

-

my application has been depending on presence of /usr/bin/arch, , understanding part of standard mac os x installation. it's there if install snow leopard dvd, without installing developer tools. however, i've encountered 2 users 10.6.7 missing file. there normal way of getting mac os x omits arch? or these users' installations happen broken?

/usr/bin/arch part of com.apple.pkg.basesystem package, should present in every stock mac os x installation. running:

$ pkgutil --file-info /usr/bin/arch

will tell package installed /usr/bin/arch, , running:

$ pkgutil --files com.apple.pkg.basesystem

will tell contents of package.

it might worth run latter in machines of users haven’t got arch.
