Ruby Forum Ruby > Shattered gems?

This seems to be a basic thing: run rails under ruby and execute the
ensuing system.  Every Ruby on Rails books or tutorial does this.
Here's what's happening for me:

First, here's my version information:

michael@isolde:~/Development/Rails$ rails --version
Rails 2.0.2
michael@isolde:~/Development/Rails$ ruby --version
ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-linux]

Here are the gems I have installed:

michael@isolde:~/Development/Rails$ gem list --local

And here's my proof that I'm up-to-date with my gems:

michael@isolde:~/Development/Rails/junk$ gem update
Updating installed gems
Bulk updating Gem source index for: http://gems.rubyonrails.org/
Nothing to update

I'm really stumped as to where to go from here.  There's no hint I can
find as to what the problem actually is except that, obviously,
something, somewhere is breaking a pretty much bog-standard Rails2
installation right out of the box.  How do I go about debugging this?
(Looking at the file that creates the error message shows me nothing
meaningful.)

Try to uninstall edge rails and recreate the project. It seems the
rails generator you called is from 2.0.2.9216 but the rails version
that is executed with script/server is version 2.0.2.

That does appear to be the problem, but now instead I have a different
problem:

Bulk updating Gem source index for: http://gems.rubyonrails.org/
Bulk updating Gem source index for: http://gems.rubyforge.org/
Bulk updating Gem source index for: http://gems.rubyonrails.org/
ERROR:  While executing gem ... (Gem::RemoteSourceException)
    Error fetching remote gem cache: Errno::EPIPE: Broken pipe reading
http://gems.rubyonrails.org/yaml

The ruby-on-rails gem site is borked.  Again.  Second time this month.
(And why is it bulk updating twice on a single pass of gem?)
