uses 1.6.0 code is the better bet. but it may not have any effect on this problem.
Maybe you should look into the gemset setup if you use rvm.

use <name>=<value> for environment variable, just like you did from command line, cannot use those values as is.
GEM_HOME=/usr/local/rvm/gems/ruby-2.1.3
GEM_PATH=/usr/local/rvm/gems/ruby-2.1.3:/usr/local/rvm/gems/ruby-2.1.3@global

I would suggest not to use RVM, it is big headache, just install ruby and gem from source, then install rails.

Your idea is like "milk doesn't have a good taste then blame a straw"
Would it be better if u offer me a debug version or way to debug the part of the code which produced this error message "
rack (LoadError) or (LoadError)" then we would know what is cause of the problem.

The error is from ruby gem, I think it is that the gem searching path was not set properly.
You can write a simple rack hello world application, see if you can run it.
like http://ruby.about.com/od/rack/a/Using-Rack.htm

RVM is for running multiple version of ruby/rails, if you only use one version, no need to bother.

Not just simple hello word script I can even run the big website project like this successfully.
https://github.com/neighborly/neighborly-donate
https://github.com/catarse/catarse
But, it was run on rail not litespeed.
