How can I convert the next line in Rails 2.3.4 to Rails 2.0.2?

config.gem ‘panztel-actionwebservice’, :lib =\> ‘actionwebservice’

I have this in my environment.rb file:  
#------------------------------------------------------------------------------  
RAILS\_GEM\_VERSION = ‘2.0.2’ unless defined? RAILS\_GEM\_VERSION

Rails::Initializer.run do |config|  
…

# to add the gem to the conf/environment.rb so that is knows the

correct actionwebservice gem  
config.gem ‘panztel-actionwebservice’, :lib =\> ‘actionwebservice’  
…  
end  
#-----------------------------------------------------------------------------

I’m doing a web service, pero I need to do it with RAILS\_GEM\_VERSION =  
‘2.0.2’

If I try to run the service, it shows the next:

Does anyone know how?

I’m using panztel-actionwebservice-2.3.5 and actionwebservice-1.2.6

Thanks and regards.
