Je viens d’avoir ce petit soucis au boulot, et comme j’ai la solution, je la partage ! :)
Une fois passé à OS X Lion, et Java installé par le Software update, j’ai donc lancé l’installation des gems d’un project Ruby On Rails ayant comme dépendance rjb.
Mais pendant son installation, voici l’erreur que j’avais:

Mon JAVA_HOME étant définie comme ceci:
1
export JAVA_HOME=$(/usr/libexec/java_home)
et donc contenant:
1
2
echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
Pour corriger ce problème, il suffit de créer un lien symbolique manquant qui ajoutera le dossier include dans le JAVA_HOME comme ceci:
1
sudo ln -s /System/Library/Frameworks/JavaVM.framework/Headers $JAVA_HOME/include
Maintenant l’installation de RJB re-fonctionne ! ;-)
