restful_clicktocall problem

Hi all,

I'm struggling to launch the Click2Call application which is nicely
described on https://github.com/jsgoecke/restful_clicktocall but it
fails to work on my system. Below my configuration:

CentOS release 5.5 (Final) Asterisk 1.4.35 + Asterisk-GUI

# gem list LOCAL GEMS

activesupport (3.0.6) adhearsion (1.0.1) bundler (1.0.11) daemons (1.1.2) eventmachine (0.12.10) git (1.2.5) i18n (0.5.0) jsgoecke-restful_adhearsion (0.1.1) json (1.5.1, 1.1.3) log4r (1.1.9) rack (1.2.2, 1.0.1) rake (0.8.7) rest-client (0.8.2) rubigen (1.5.6) rubygems-update (1.7.2) sinatra (1.2.1) thin (1.2.11) tilt (1.2.2)

# cat /etc/asterisk/manager.conf . . . [ahn_ami] secret = iheartlolcats read = system,call,log,verbose,agent,user,config,dtmf,reporting,cdr,dialplan
write = system,call,agent,user,config,command,reporting,originate

I followed all the steps mentioned in the brief tutorial on a/m
webpage (all commands executed as root):

# gem install jsgoecke-restful_adhearsion --source=http:// gems.github.com/
# ahn create click2call # cd click2call/components/ # git clone git://github.com/jsgoecke/restful_clicktocall.git # cd .. # cat dialplan.rb

  adhearsion {
     self.call.variables[:destination] = get_variable("destination")
     dial self.call.variables[:destination]
   }

# ahn enable component restful_rpc

# vi /config/startup.rb (and uncommented below lines of code)

   config.enable_asterisk :argument_delimiter => '|'
   config.asterisk.enable_ami :host => '127.0.0.1', :username =>

'ahn_ami', :password => 'iheartlolcats', :events => true

And when trying to run the whole app, the following error occurs:
# ahn start . ERROR: restful_rpc requires the 'rack' and 'json' gems

Log file (click2call /log/adhearsion.log) doesn’t show anything, rack
and json gems are both installed so I do not have any clue what might
be wrong.

Obviously, when I run "ruby run_me.rb" in /components/
restful_clicktocall/web and try to invoke that service from http://localhost:4567,
it also results in a stack of exceptions:
