Problem running executable in debugger on Mac OS Mavericks

[Cyrille Artho]

Hi all,
I have tried to build rtems-builder and rtems following the "Quick Start" 
instructions on the web page. It seems I can build executables as I can 
find "ticker.exe". However, I cannot run it as shown.

"tar sim" is not recognized; it seems the simulator is not built correctly. 
Below is the output from gdb. What went wrong?
I also don't have a binary called "i386-rtems4.11-run", which is mentioned 
on the quick start guide as well.
