Subject: need quick check on my rubygems install procedure

I'm running Kubuntu Linux 8.10 - a fresh install. I'm setting up Ruby now.

I've done this before, but it takes very little for me to be in over my 
head, so I need a quick review from someone who actually 'has a clue'.

I have just installed Ruby 1.8.7 from the source available at the Ruby 
website. No problems. I then downloaded from Rubyforge the 
rubygems-1.3.1.tgz module, unpacked it, and launched its setup.rb file. 
There was no console response other than a new command line. I assume 
this is normal.

Then....I issue a gem -v, and get back "1.2.0".

I'm lost at this point. I thought I just installed v. 1.3.1.

"which gem" produces "/usr/bin/gem".

Looking there, I see both a "gem" and a "gem1.9".

Oh boy. Two versions. "gem1.9 -v" also produces "1.2.0". Now I'm really 
confused. And why "gem1.9"? What's THAT about?

Being very suspicious at this point, I issue "which ruby1.9" and get 
back "/usr/bin/ruby1.9". "ruby1.9 -v" produces "ruby 1.9.0 (2008-06-20 
revision 17482) [i486-linux]". This is just nuts. I didn't install this. 
Where did it come from?

If I'm going to use my new Ruby 1.8.7 and want it to use the latest 
rubygems, which I presume IS somewhere in my filesystem, what do I need 
to do? Anything at all?

Can someone please untangle this for me, so I can just get back to work 
with my ruby learning...?

Thanks (very much!) in advance.

Tom
