Thinking that maybe I should install manually from a downloaded rubygems, I uninstall it again, then download rubygems-1.0.1.tgz from rubyforge, unpack it, and issue...  
  
:/$ ruby setup.rb  
  
I get a glorious pile of output, of which these are the first two lines:  
  
&nbsp;&nbsp;&nbsp; install -c -m 0644 rubygems/rubygems\_version.rb /usr/local/lib/site\_ruby/1.8/rubygems/rubygems\_version.rb  
&nbsp;&nbsp;&nbsp; install -c -m 0644 rubygems/dependency\_list.rb /usr/local/lib/site\_ruby/1.8/rubygems/dependency\_list.rb  
  
Reading through all of this, I nothing that looks like something went badly wrong - except this:  
&nbsp;&nbsp;&nbsp; Skipping RDoc generation, /usr/lib/ruby/gems/1.8/doc not writable  
&nbsp;&nbsp;&nbsp; Set the GEM\_HOME environment variable if you want RDoc generated&nbsp;&nbsp;&nbsp;&nbsp;   
How do I do that?  
  
All of this is happening in a console launched in my user account Desktop folder. Still there, I decide to test the install, as before, and issue  
:/$ gem help  
  
I get...  
:/$ The program 'gem' is currently not installed.&nbsp; You can install it by typing:  
:/$ sudo apt-get install rubygems  
  
How can this be? Didn't I just install it? It sure looked like it. How can I fix this?  
  
Thanks for any and all help.
