Hallo everybody,  
I am trying to move one application from one server to another both  
running Suse 10.2 64Bit (one is a SLES one is Open Suse). I’ve tried to  
reinstall all packages on both machines (so that they both are running  
Ruby 1.8.6 X64, Rails 1.1.6 with the related gems), the app is using  
Mongrel Cluster to run.  
On the old server it runs smoothly but on the new server i don’t get it  
to run.

In the environment.rb file there is a line:

# user erubis as rendering engine

require ‘erubis/helpers/rails\_helper’

If I leave it uncommented I get the following error in the Mongrel log  
file when launching Mongrel:

\*\* Daemonized, any open files are closed. Look at  
tmp/pids/mongrel.4000.pid and log/mongrel.4000.log for info.  
\*\* Starting Mongrel listening at 0.0.0.0:4000  
\*\* Starting Rails with production environment…  
/usr/lib64/ruby/gems/1.8/gems/erubis-2.4.0/lib/erubis/helpers/rails\_helper.rb:112:  
uninitialized constant ActionView (NameError)  
from  
/usr/lib64/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:32:in  
`gem\_original\_require’  
…

and Mongrel doesn’t start. erubys is installed (the same version (2.4.0)  
on both machines). I’ve also tried to update erubys to the latest  
version but did not make any difference.

If I comment the line, I get the following in the Mongrel Log File:  
\*\* Daemonized, any open files are closed. Look at  
tmp/pids/mongrel.4000.pid and log/mongrel.4000.log for info.  
\*\* Starting Mongrel listening at 0.0.0.0:4000  
\*\* Starting Rails with production environment…  
\*\* Rails loaded.  
\*\* Loading any Rails specific GemPlugins  
\*\* Signals ready. TERM =\> stop. USR2 =\> restart. INT =\> stop (no  
restart).  
\*\* Rails signals registered. HUP =\> reload (without restart). It might  
not work well.  
\*\* Mongrel available at 0.0.0.0:4000  
\*\* Writing PID file to tmp/pids/mongrel.4000.pid

and I can reach the login page of the Ruby Application, but then  
whatever login name/password I enter (correct or not) it tells me (login  
unsuccessful) and it returns to the login page:
