Hello RubyComminity !!!

I have decided to move to ruby to make the util script I usually do in  
Perl.  
I need to create a graph from an XML file.  
For this, it seems that I can use gruff and magic/xml (not sure this  
is the best choice as I am not familiar with those libs).

I have installed the gruff gem, that went fine.  
Regarding magic/xml I have unzip the install and copy the folder in  
“C:\ruby\lib\ruby\1.8” (is that enought ???)

Then I tried the gruff example:

* * *

#!/usr/bin/ruby

require ‘rubygems’  
require ‘gruff’

g = Gruff::Line.new  
g.title = “My Graph”

g.data(“Apples”, [1, 2, 3, 4, 4, 3])  
g.data(“Oranges”, [4, 8, 7, 9, 8, 9])  
g.data(“Watermelon”, [2, 3, 1, 5, 6, 8])  
g.data(“Peaches”, [9, 9, 10, 8, 7, 9])

g.labels = {0 =\> ‘2003’, 2 =\> ‘2004’, 4 =\> ‘2005’}

g.write(‘my\_fruity\_graph.png’)

* * *

But I get the following error…

Gem::LoadError: Could not find RubyGem hoe (\>= 1.1.2)

Do you have an idea of what went wrong ?  
Also, I have to install all the gem locally as I am behind a proxy (do  
not know if this can be linked)

Thanks a lot,

Luc
