Problems with installing gems

Hi!

I'd like to installed gem with

sudo gem install rails

By default, the rails gem should go into /usr/lib/ruby/gems/1.9.1, but it goes to /root/,gem:

  [ram@thingol:~]sudo gem install rails --no-rdoc
Password:
WARNING: You don't have /root/.gem/ruby/1.9.1/bin in your PATH,
       gem executables will not run.
Successfully installed rails-3.2.2
1 gem installed
Installing ri documentation for rails-3.2.2...
Updating ri class cache with 1090 classes...

Even if I give it the --install-dir option, it does the same:

[ram@thingol:~]sudo gem install rails --no-rdoc --install-dir /usr/lib/ruby/gems/1.9.1 [13:46:27|12-03-16]
WARNING: You don't have /root/.gem/ruby/1.9.1/bin in your PATH,
       gem executables will not run.
Successfully installed activesupport-3.2.2
Successfully installed rails-3.2.2
2 gems installed

I like the use the $HOME/.gem location for running test as a regular user, but not for root. Here is my gem env:

[ram@thingol:~]gem env [13:49:26|12-03-16]

the line with - "gem" => "--user-install" looks suspicious, but how can I change it? Did I do a misconfiguration. I have no .gemrc file.

Any help is welcome!

Look for ~/.gemrc

And then /etc/gemrc

You (in your profile) or your distro might be setting --user-install
there.

Thats it! /etc/gemrc contains

gem: --user-install

Thanks a lot
