Problema de permissão negada na atualização cocos2d

Question

Eu tenho tentado atualizar para a versão 2 do Cocos2D, mas sempre recebo as seguintes linhas de código no terminal.

Installing Xcode 4 Box2d iOS template
-------------------------------------------------

mkdir: /Users/jubilate/Library/Developer/Xcode/Templates/cocos2d v2.x: Permission denied   ...copying Box2d files
rsync: mkdir "/Users/jubilate/Library/Developer/Xcode/Templates/cocos2d v2.x/lib_box2d.xctemplate/libs" failed: No such file or directory (2)
rsync error: error in file IO (code 11) at /SourceCache/rsync/rsync-42/rsync/main.c(544) [receiver=2.6.9]
rsync: connection unexpectedly closed (8 bytes received so far) [sender]

done!

Installing Xcode 4 CCNode file templates...
----------------------------------------------------

...creating destination directory: /Users/jubilate/Library/Developer/Xcode/Templates/File   Templates/cocos2d v2.x/
mkdir: /Users/jubilate/Library/Developer/Xcode/Templates/File Templates/cocos2d v2.x: Permission denied
mv: rename /Users/jubilate/Library/Developer/Xcode/Templates/cocos2d v2.x//CCNode    class.xctemplate to /Users/jubilate/Library/Developer/Xcode/Templates/File Templates/cocos2d v2.x/:   No such file or directory
done!

Eu instalei usando o comando

./install-templates.sh -u -f

E também excluiu pastas que começam com "cocos2d" (versão anterior) em:

~/Library/Developer/Xcode/Templates/cocos2d*
~/Library/Developer/Xcode/Templates/File Templates/cocos2d*

Alguém poderia me ajudar?

Eu tenho trabalhado nisso por dias.
