Question: `/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/universal-darwin13/rbconfig.rb:213: warning: Insecure world writable dir /usr in PATH, mode 040777`

I've tried these two commands after searching for solutions on Stackexchange, but it didn't work for me. It still shows me the warning which I've pasted above.

```
sudo chmod 775 /usr/local

sudo chmod go-w /usr/local/bin

```

How do I fix this warning message? I'm running OS X 10.9 Mavericks

Answer: 
I fixed this by using Disk Utility to repair disk permissions.

Open the Disk Utility application and select the disk your system is installed on. Then you can select "Repair Disk Permissions" from the First Aid tab. Repair will take a couple of minutes
Executing the following worked for me on Mac OS X 10.11 El Capitan

`sudo chmod o-w /usr/local`

The error occured when loading a vagrant as follows;

`vagrant status
/opt/vagrant/embedded/gems/gems/vagrant-1.8.1/lib/vagrant/pre-rubygems.rb:31: warning: Insecure world writable dir /usr/local in PATH, mode 040777
/opt/vagrant/embedded/gems/gems/bundler-1.10.6/lib/bundler/shared_helpers.rb:78: warning: Insecure world writable dir /usr/local in PATH, mode 040777
ls -dal /usr/local/
drwxrwxrwx 10 root wheel 340 Sep 9 15:05 /usr/local/`

After running the chmod mentioned above.

`ls -dal /usr/local/
drwxrwxr-x 10 root wheel 340 Sep 9 15:05 /usr/local/`

Which solved the problem.
