Subject: Re: RubyGems 1.0.0

Ok, i solved the problem (i had it in many computers, all of them 
Ubuntu). The problem was /usr/bin/gem is not updated. Seems all the 
files but /usr/bin/gem are updated to 1.0.1

First of all:

gem update --system

I renamed all de /usr/local/bin/gem* to /usr/local/bin/gem*.bak (if 
any). All the good bins are in my /usr/bin/gem* (only one place)

Then i overwrite that /usr/bin/gem with an updated copy. I put here the 
contents of an 1.0.1 /usr/bin/gem script if anyone wants to manually 
copy-paste it:

require 'rubygems'
require 'rubygems/gem_runner'

required_version = Gem::Requirement.new ">= 1.8.2"

unless required_version.satisfied_by? Gem::Version.new(RUBY_VERSION) 
then
  abort "Expected Ruby Version #{required_version}, was #{RUBY_VERSION}"
end

# We need to preserve the original ARGV to use for passing gem options
# to source gems.  If there is a -- in the line, strip all options after
# it...its for the source building process.
args = !ARGV.include?("--") ? ARGV.clone : ARGV[0...ARGV.index("--")]

Gem::GemRunner.new.run args
#-------------------------------------------------------------------------

After that, all the problems are gone:

# gem -v
1.0.1
