Why isn't bundle install allowing for the pg gem to fully install?

I've installed the pg gem as shown, but...

Building native extensions.  This could take a while...
    Successfully installed pg-0.11.0
    ERROR:  Could not find a valid gem '—' (>= 0) in any repository
    ERROR:  Could not find a valid gem '–with-pg-config=/usr/local/pg/bin/pg_config' (>= 0) in any repository
    1 gem installed
    Installing ri documentation for pg-0.11.0...
    Installing RDoc documentation for pg-0.11.0...

Something strange happens when I bundle install and it won't completely install the pg gem:

Fetching source index for http://rubygems.org/

Then I get the lines that tell me I may lack necessary libraries or headers:

   *** extconf.rb failed ***
    Could not create Makefile due to some reason, probably lack of
    necessary libraries and/or headers.  Check the mkmf.log file for more
    details.  You may need configuration options.

Here is my gem file:

  source 'http://rubygems.org'

gem 'rails', '3.0.10'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'pg'
gem 'gravatar_image_tag', '1.0.0.pre2'
gem 'will_paginate', '3.0.pre2'



group :development do
  gem 'rspec-rails', '2.6.1'
  gem 'annotate', '2.4.0'
  gem 'faker', '0.3.1'
end

group :test do
  gem 'rspec-rails', '2.6.1'
  gem 'webrat', '0.7.1'
  gem 'spork', '0.9.0.rc8'
  gem 'factory_girl_rails', '1.0'
end

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'

# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end

How do I solve this issue? Thanks in advance.

EDIT Answer:The trick was to install the pg gem under the correct pathway to pg_config whereas before it wasn't fully installed. I ran 'gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config ' for the path I had put down under my last comment. I just had to locate my pg_config file and run gem install under that.

For Windows and as-of version 0.13.0 of the pg gem, you should be able to install it using something like the following:

subst X: "C:\Program Files\PostgreSQL\9.0"
gem install pg -- --with-pg=X:
subst X: /D

Then you can successfully run bundle install and see the following line in the output:

Using pg (0.13.0)

instead of the errors.

[This is the same answer as this answer to the related question Can't install pg gem on Windows.]

I ran gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config after locating the pg_config exec file. I just had to locate my pg_config file and run gem install under that pathway.
