users have reported this on the support list as well)

test of Node.js the warning is triggered.

OS X is a mess of symlinks that eventually arrive at
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home anyway.

give the user the option to set either their JAVA_HOME themselves and/or
manage their own JVM installs (say, for those using openjdk or other
'non-apple' java versions, which by the looks of it will soon be
everyone...) plus, for now, at least in recent versions of os x the default
behavior is correct.

get it to build yet.. (git clone and ant bails out) So I don't have a patch
or anything I can send for this, but just thought I'd send it over in the
hope that it will help :)

with the build and trying to familiarise myself with what is already there,
as I said I hope to be able to make a contribution as time goes on and will
probably pop up again sooner or later either here or on irc looking for some
direction into where I can help out.
