Rubygems 0.9.4 problem on Ubuntu drake

Hi all,

I’ve just installed RubyGems 0.9.4 from source (not thru apt-get
package) under Ruby 1.8.6 (also source install) and everything went

But, upon first usage, say installing Rails via:

gem install rails --include-dependencies --debug

I’ll get a whole whackload of Exception ‘NameError’ from
command_manager.rb:145 - uninitialized constant
Gem::Commands::BuildCommand (and every other possible command).

The file command_manager.rb file (located at:
/usr/local/lib/ruby/site_ruby/1.8/rubygems) line 145 is doing this:


And that’s called once per command that’s defined in the commands
directory resulting in errors like these:

Exception NameError' at /usr/local/lib/ruby/site_ruby/1.8/rubygems/command_manager.rb:145 - uninitialized constant Gem::Commands::BuildCommand ExceptionNameError’ at
/usr/local/lib/ruby/site_ruby/1.8/rubygems/command_manager.rb:145 -
uninitialized constant Gem::Commands::CertCommand
Exception `NameError’ at
/usr/local/lib/ruby/site_ruby/1.8/rubygems/command_manager.rb:145 -
uninitialized constant Gem::Commands::CheckCommand

Here’s my rubygems environment from gems itself

RubyGems Environment:

  • VERSION: 0.9.4 (0.9.4)
  • INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8
    • /usr/local/lib/ruby/gems/1.8

And here’s my PATH environment variable:

I’m running linux under Ubuntu 6.06.1, fresh install, with Ruby 1.8.6
compiled from source and extended with zlib library.

Anyone have any ideas of what’s going on here?

Many thanks,
