Sqlite gem not found with rails3


I am migrating a rails app to rails3, however I am hanging with an
error about gem not found.

   Error message:
   Could not find sqlite3-ruby-1.3.2 in any of the sources
   Exception class:

When I do

   $ gem list sqlite3-ruby-1.3.2
   *** LOCAL GEMS ***
  (and the same result with sudo gem list )

However, when I do

   gem list sqlite3-ruby
   *** LOCAL GEMS ***
   sqlite3-ruby (1.3.2, 1.3.0)

How can I make rails3/passenger environment see the right gems?
How can I make sure that passenger calls the right ruby environment?

The stack trace from the error is:

try these ways:

1. reinstall your Runygem; waht is your version now for "gem -v"? If
you have Ruby 1.9 ("ruby -v"), you should have 1.3.7, with Ruby 1.8
Gem1.3.5. I suggest use the updated versions.

2. Do you used your "gem 'sqlite3-ruby'" in your Gemfile, and then run
bundle install?

3. Use RVM. http://rvm.beginrescueend.com/
Here your problem is your gem path is still for older version of Ruby
(I assume that you updated). With RVM you can have multiple versions,
and all confusion will disappear.

If you have further problem with it write me in private with these
details please: ruby -v, gem -v, gem list, OS.
Good luck,
