I'm using:

• Windows 7
• Ruby 1.8.6 One-Click Installer
• DBI version 0.4.3 installed using RubyGems

What I see when executing these commands:

C:>ruby -v

ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]

C:>gem -v

1.3.1

C:>ruby -r rubygems -r dbi -e "puts DBI::VERSION"

0.2.2

C:>gem list dbi

*** LOCAL GEMS ***

dbi (0.4.3)

Why do ruby scripts use the DBI installed in site_ruby rather than the DBI installed with RubyGems?

Updated to respond to Luis Lavena's answer...

Here's what happened when I attempted what you suggest:

C:>ruby -r rubygems -e "require 'rubygems'; puts DBI::VERSION"

-e:1: uninitialized constant DBI (NameError)

And when I updated to require DBI:

C:>ruby -r rubygems -e "require 'rubygems' ; require 'dbi' ; puts DBI::VERSION"

0.2.2

Why wouldn't RubyGems override the built-in library?
