For the millionth time, cause I always forget...
Put this in ~/.bashrc:
export JAVA_HOME=/Library/Java/Home
[UPDATE: or this, which according to Mike Swingler, follows the Java version chosen in Java Preferences:
export JAVA_HOME=`/usr/libexec/java_home`
]
Also, run "sudo visudo" and add the line
Defaults env_keep += "JAVA_HOME"
or else commands like "sudo gem install" won't be able to find Java.
Without the above, I got the following error (which seemed to have been run through a baby-talk filter) when running "sudo gem install rjb":
extconf.rb:44: JAVA_HOME is not setted. (RuntimeError)
