Some os commands (ls, ping...) not working after bootstrap

[fleveque]

I'm having some trouble with my forked repo on my macOS Sierra. After installing, some commands like ls or ping don't work:

🔌 1:11 in .dotfiles/ on master
› ls
Traceback (most recent call last):
File "/usr/local/Cellar/grc/1.10_1/libexec/bin/grc", line 191, in

exec_func(fullname, *argrest)
FileNotFoundError: [Errno 2] No such file or directory

Does anybody have a clue about what could be the problem?
