Alternative Rails installation method?

Hi There,

I am trying to install rails via gems and as Rubyforge appears to be
down this is not working for me.

I have searched around and also tried installing from Mirrors - I get
error messages:

sudo gem install rails --include-dependencies --source
http://gems.dpiddy.net/
ERROR: While executing gem … (Gem::RemoteSourceException)
HTTP Response 404

sudo gem install rails --include-dependencies --source
http://ftp.iasi.roedu.net/mirrors/rubyforge.org/
ERROR: While executing gem … (Gem::RemoteSourceException)
HTTP Response 404

I am new to all this and might well be doing something wrong. If not is
there any other way to install?

Thanks,
Vince
