"Error: JAVA_HOME is not defined correctly." in building Jikes rvm

When I built the Jikes RVM on Unbuntu, I got this error. Any idea?

bin/buildit localhost production

I checked the

directory, it works.
No matter how I change the environmental variables, the error kept complaining "We cannot execute /opt/jdk1.6.0/bin/java". It seems that I didn't modify the right "position".

Any clue?

run this command:

To find out which file is setting JAVA_HOME to that path.
