Gem ne fonctionne pas après la mise à jour vers OS X 10.10 Yosemite Beta

Question

J'ai du mal à faire fonctionner la gemme après la mise à jour de 10.10 Yosemite.

L'exécution de cette (ou tout autre gem install/désinstallation):

sudo gem install mysql2psql 

Et ce serait toujours me donner l'erreur suivante:

/Library/Ruby/Site/2.0.0/rubygems/ext/builder.rb:159:in `synchronize': ERROR: Failed to build gem native extension. (Gem::Ext::BuildError) 

    ERROR: Failed to build gem native extension. 

    deadlock; recursive locking

Peut-être que quelqu'un peut vous aider! Xcode 6 beta installé, y compris les outils de ligne de commande.

Merci beaucoup à l'avance!

J'ai eu le même problème, et a résolu le problème en supprimant mes Gems, et en réinstallant:

sudo rm -rf /Library/Ruby/Gems/*; 
sudo gem update --system 

(comme décrit here)
