Rails - Jun 2009 - install pb(solved) : http://gems.rubyforge.org/ does not appear to be a repository

I''m installing ruby on rails on my local windows laptop,
piece of cake, ruby is adult now, so I thought...

http://rubyonrails.org/download
is clear :
install ruby with windows installer, ok
download gems, unzip and  "ruby setup.rb", ok
but "gem install rails" tells :
"http://gems.rubyforge.org/ does not appear to be a repository"
here I groan, is it the proxy ? no, is it a real message ?
(gems.rubyforge is not a repository!?). what are those kind of
incomplete installations.
in google many people are in the same sh..case.

the solution :

1) it is a connection problem to repository :

gem install rails --debug

error message should be  "Timeout" instead of "not a
repository"

checking : yes unfortunately the site seems overloaded , unbrowseable
http://gems.rubyforge.org/gems

2) http://gems.rubyforge.org should be multimirrored
yes there are mirrors, but where there is only few gems, 25 on gem
list --source http://gems.rubyonrails.org

3) I managed installing gems manually.
but not like the other posts I will tell how  (to just a  "I
succeeded! thanks!")
gem install rails --source http://gems.rubyonrails.org
indicates that  "rake" is not up to date, I found a mirror
http://de.mirror.rubyforge.org/gems/ and downloaded rake-0.8.7.gem,
and
gem install rake-0.8.7.gem
then
gem install rails --source http://gems.rubyonrails.org

4) so..... three hours lost, because of the installation system not
working.
-http://gems.rubyforge.org is supposed to lead to other mirrors ? this
is not working.
-in the basic installation there is no backup repositories
-there is no manual list of mirrors
=> guys, you have already built all the tools , you can do as reliable
as CPAN or CentOs
