Unable to install rjb on mac, no header directory in /System/Library/Frameworks/JavaVM.framework/Headers

Question

When I install rjb on mac, there is some error, as follows: Building native extensions. This could take a while... ERROR: Error installing rjb: ERROR: Failed to build gem native extension.

    /Users/twer/.rvm/rubies/ruby-1.8.7-p352/bin/ruby extconf.rb


extconf.rb failed

Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Provided configuration options:

--with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/Users/twer/.rvm/rubies/ruby-1.8.7-p352/bin/ruby
extconf.rb:45:in `open': No such file or directory - /System/Library/Frameworks/JavaVM.framework/Headers (Errno::ENOENT)
    from extconf.rb:45

Gem files will remain installed in /Users/twer/.rvm/gems/ruby-1.8.7-p352@home-ideas/gems/rjb-1.3.3 for inspection. Results logged to /Users/twer/.rvm/gems/ruby-1.8.7-p352@home-ideas/gems/rjb-1.3.3/ext/gem_make.out

Then I try to install Java developer package to solve the problem. But there is still no/System/Library/Frameworks/JavaVM.framework/Headers directory.
Please help me.

I just installed rjb, but I'm on 1.9.3-p327... Perhaps rvm install 1.9.3-p327 and see how you get on?
