require': no such file to load -- rubygems (LoadError)
Would some of you guru's be so kind as to help me (a) fix the
above problem and (b) point out some of the other things I
need to install - like mysql gateways, etc. Pointing me at
where to get them would be greatly appreciated, too.
RubyGems is the de facto way to distribute Ruby
packages/addons/extensions/libraries/whatever. Even RubyGems is
distribute as a gem. The first problem for you to solve is
bootstrapping this loop. The process of installing RubyGems by
hand is explained in [1].
Once that is done, you can use "gem search mysql -r" to find
the gem you want and use "gem install mysql" to install this
stone.
Life easy, when you know how where to start...

...and I'll admit to being new enough that I have *NO IDEA* where to
start. <g>
I went to the site you referenced and downloaded rubygems 0.9.0. I
untarred it, went to the directory and (as root) ran ruby setup.rb -
which is what the site said to do. It ran a bit, then gave me the
following error:
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require': no such file to load -- zlib (LoadError)
I did see the note about installing libzlib, but when I tell apt to do
so, it says that it is installed and at the latest version. Obviously
something is still missing.
All help *GREATLY* appreciated.

What's the output of this?:
$ find `ruby -r rbconfig -e 'puts Config::CONFIG["archdir"]'` | grep
-wie zlib

I think you've put your finger on the problem. The above command has no
output. Looking closer, I see that ruby is apparently looking for
zlib.so under /usr/local/lib/ruby/1.8/i686-linux.
The library is actually under /usr/lib/ruby/1.8/i486-linux/zlib.so (as
placed by my distribution). This, of course, brings up the question of
how to correct this. I need to either (a) Tell ruby where the libraries
are, (b) Move the libraries to where ruby thinks they are, or (c)
Recompile ruby to be in /usr/bin - which is where the distribution put
it. To me, (c) looks the least error prone - but I'm sure willing to
listen to other suggestions. Almost everyone here knows more about ruby
than I do.
Thanks - and all help is appreciated

You may have done some of this already, so disregard the parts that already
apply:
Me personally, I get the latest stable-snapshot. It is Ruby 1.8.5.
Extract the source somewhere.
cd into that directory where you extracted the source.
Edit ext/Setup
uncomment zlib, ssl, readline
apt-get the following packages:
build-essential
zlib1g-dev
readline5-dev
ncurses-dev
and when I install Ruby from source, I want it to go into /usr/bin rather
than /usr/local/bin, so I set
./configure --prefix=/usr in the first stage
then make
then sudo make install

The Ubuntu distribution release of the mysql driver for ruby doesn't
seem to work with a compiled version of ruby. I tried installing it with
sudo gem install mysql
It asks me which version to install, and I chose the latest non-windows
version. It then runs a bit and I get the following error
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
I'm sure this tells those of you who have been around a bit a lot, but
I'm brand new to gems. How do I address getting the mysql library up.
Also, are there other gems that I should consider installing as well.
Thanks again

Well, uh, what does mkmf.log tell you?... ;]
Have you installed the MySQL development packages? You can find
them with "apt-cache search mysql | grep -ie mysql.*dev".

Lesson one when installing Ruby on Ubuntu: Remove all default
Ruby packages that come with Ubuntu and compile everything
yourself.

When you install Ruby from source it would be better to include --prefix=/usr/local/ruby
And update your path to include /usr/local/ruby/bin before /usr/bin and you don't have to worry about what ever packages have been installed for your distro.
