nagios_var insufficient for distribution packages (in this case debian/squeeze)

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Install the following packages (and possible dependencies) on debian testing 
(squeeze):
ii  icinga                            1.0.2-1                           
monitoring and host and network monitoring system - metapackage
ii  ruby1.8                           1.8.7.299-1                       
Interpreter of object-oriented scripting language Ruby 1.8
ii  libmetaid-ruby1.8                 1.0-5                             Some 
additional methods to make metaprogramming easier
ii  libxmpp4r-ruby1.8                 0.5-1                             
XMPP/Jabber library for Ruby
ii  libsinatra-ruby1.8                1.0.really1.0-1                   Ruby 
web-development dressed in a DSL
ii  mongrel                           1.1.5-5                           A small 
fast HTTP library and server for Ruby

2. edit config file (btw: var directory for icinga debian package is 
/var/lib/icinga - checked to contain status.dat and rw directory)
3. launch "./molniya -c icinga.yaml"

What is the expected output? What do you see instead?
expected:
Molniya entering stable orbit around Icinga with downlink to xmpp server.

actual output:
./nagios.rb:508:in `load': undefined method `hosts' for nil:NilClass 
(NoMethodError)
        from ./nagios.rb:159:in `_refresh'
        from ./nagios.rb:127:in `refresh_if_needed'
        from /usr/lib/ruby/1.8/monitor.rb:242:in `synchronize'
        from ./nagios.rb:124:in `refresh_if_needed'
        from ./nagios.rb:438:in `refresh_if_needed'
        from ./nagios.rb:164:in `contents'
        from ./molniya.rb:437:in `status_report'
        from ./molniya.rb:599:in `update_status_msg'
        from ./molniya.rb:524:in `initialize'
        from ./molniya.rb:765:in `new'
        from ./molniya.rb:765:in `launch'
        from -e:1

What version of the product are you using? On what operating system?
molniya 0.3 for further info see top.

Please provide any additional information below.
Turns out that the presumption that both 'status.dat' and 'object.cache' live 
both in 'nagios_var' is wrong in case of debian packages (both for nagios3 
_and_ for icinga!). 
I helped myself with an 'ln -s /var/cache/icinga/objects.cache 
/var/lib/icinga/objects.cache'. Though a more flexible solution would be 
preferred.
I'd provide a patch, but I've never touched ruby before, sorry.

this patch and using

nagios_var: /var/lib/nagios3/
nagios_cache: /var/cache/nagios3/

in the config.yaml makes things go further for me.

also i can recommend installing rubygems1.8 from backports for lenny to get 
ruby going.
