Issue with creating a symbolic link inside /System folder I am trying to make a symbolic link inside the /System folder and even if I run the command as su I get the following error message.

macbook-pro:~ root# cd /System/Library/Perl/Extras/5.18 
macbook-pro:5.12 root# ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/SVN/ SVN 
ln: SVN: Operation not permitted
macbook-pro:5.12 root# ls -ld /System
drwxr-xr-x@  4 root  wheel restricted 136 Sep 22 10:37 System


How can I get this working?
I am guessing you are doing this to get git-svn to work. I've tested this on git 2.6.2. If so, link to non restricted directory:

sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/SVN/ /Library/Perl/5.18/SVN
sudo mkdir /Library/Perl/5.18/auto
sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/auto/SVN/ /Library/Perl/5.18/auto/SVN
