Comment (by vbraun):
I've added the full path name since it can't hurt.
Upon reflection, I think this is the reason why it does not and cannot
work on OSX. In order to protect their precious DRM, Apple has disabled
much of the ptrace API. A consequence is that /usr/bin/gdb needs special
permissions (it is setgid on OSX, but a normal program on Linux) to fully
function. And the dynamic linker disallows library interposition for
setgid binaries. In fact, /usr/bin/gdb on osx is a shell script that
unsets `DYLD_*` variables before the dynamic linker even gets a chance to
complain about them.
