Problem installing rails with rake/gem


Hi all,
I am a newbie to ruby and gems and rails …
I have ruby
ruby 1.8.3 (2005-09-21) [i686-linux]

As far as i understand, gem is a package manager. something like rpm.
So I assume that it should be possible to install rails using

  1. the tgz and then running rake (I installed rake 0.6.2 )(like
    building from source)
  2. Download the rails-0.14.3.gem file and then install with gem ( like
    installing an rpm from the rpm package)
  3. use gem and download and update/install everything from the net. (
    This is my last option as my connection keeps going down)

What I did was to first try installing ruby and then rake
successfully,then unzip rails-0.14.3.tgz
and run rake on the Rakefile distributed.
It didnt work …Got the following errors.

/usr/local/src/rails > rake
(in /usr/local/src/rails)
/usr/local/bin/ruby -Ilib:test
rake aborted!
Test failures

Second I installed rubygems from rubygems-0.8.11.tgz .All i did was to
ruby setup.rb
that worked .

But now whenever I type
I get this error

/usr/local/bin/gem:3:in `require’: No such file to load – rubygems
from /usr/local/bin/gem:3

Does anyone have a clue.?
