$ run-safari Starting Safari with DYLD_FRAMEWORK_PATH set to point to built WebKit in /Users/ap/WebKit/WebKitBuild/Debug. *error: arch takes no arguments Looks like this was caused by <http://trac.webkit.org/changeset/41696>. It isn't immediately clear to me how to fix it.
The solution is to not use 'arch' to run binaries on Tiger, since it's never necessary and doesn't work in the same way it does on Leopard and beyond.

It may be better to skip setting $architecture at all on Tiger, like we do on non-Mac platforms, since I don't think it's ever useful on Tiger. This will also avoid having to check for Tiger at places that it is used.
Committed r42142. > It may be better to skip setting $architecture at all on Tiger I'm pretty much happy with getting my run-safari back. Would you be willing to work on further improving this?
I don't have a Tiger machine to test anything on, so it's not likely I'll be doing anything on this.
