Mac user and getting WARNING: Nokogiri was built against LibXML version 2.7.8, but has dynamically loaded 2.7.3

Question

I have done all kinds of research and tried many different things. I know this question has been answered many times, but none of the suggested solutions are working for me.

After upgrading to Lion I am getting segmentation faults in Ruby. I'm fairly confident it's Nokogiri. So I installed libxml2 via Homebrew. I ran brew link libxml2. Then I reinstalled Nokogiri using that version of the library.

For proof:

$ nokogiri -v
# Nokogiri (1.5.0)
---
warnings: []
nokogiri: 1.5.0
ruby:
  version: 1.9.2
  platform: x86_64-darwin11.0.0
  description: ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.0.0]
  engine: ruby
libxml:
  binding: extension
  compiled: 2.7.8
  loaded: 2.7.8

I've already included Nokogiri at the top of my gemfile and I've also required it in my environment file. I have no idea why I am still getting that warning.

Any suggestions or ideas to make sure it's loading the right version libxml2?

If you installed Nokogiri with gem install nokogiri, you can resolve this warning by running gem pristine nokogiri to recompile the gem's C extension.

If you installed Nokogiri with bundle install, you can resolve this warning by running bundle exec gem pristine nokogiri to recompile the C extension of the gem wherever Bundler installed it.
