Hi, Chauk-Mean and all -
I have just ported everything to 10.04 ubuntu, and I am pleased to note
that
I was able to use prepackaged stuff almost everywhere.
Yes, it was painful before I figured it out. 
I used apt-get to install ruby-1.8.7, all the wx libraries (including
the
dev header packages)
I uninstalled the debian rubygems package completely and installed
rubygems-1.4.1 from the source.
I then installed everything else (including wxruby-2.0.1) from gems. The
gem
manager does not appear to be able to work its way through a proxy
server,
so I downloaded all the necessary gems by hand.
Attached is the pertinent code from my installer script.
puts "Installing Ruby tools, SWIG and wxWidgets development
libraries"
puts " ( This may take a little while )"
%x{ apt-get install -y ruby1.8-dev rake swig }
%x{ apt-get install -y --reinstall libgtk2.0-0 libgtk2.0-dev }
%x{ apt-get install -y --reinstall libwxbase2.8-0 libwxbase2.8-dev
libwxbase2.8-dbg }
%x{ apt-get install -y --reinstall wx-common libwxgtk2.8-0
libwxgtk2.8-dev }

FileUtils.cd ‘/usr/local/etc’ do
puts “Installing updated RubyGems package manager.”
%x{ tar -zxvf rubygems-1.4.1.tgz }
FileUtils.cd ‘./rubygems-1.4.1’ do
%x{ ruby ./setup.rb }

%x{ rm /usr/bin/gem }
%x{ ln -s /usr/bin/gem1.8 /usr/bin/gem }
end

end

%x{ tar -zxvf prawn.tgz }

%x{ rake }

%x{ gem install prawn-0.11.1.pre.gem }
end
FileUtils.rm %w( rubygems-1.4.1.tgz ruby-sysvipc-0.9.1.tar.gz
prawn.tgz )
end
