undefined method `highlight' Python+Pygments

Question

I am using python 2.6.6 and Pygments version 1.4 on RHEL 6 i386 but always get this error message when I try to create a new project in gitlabhq.

gem list reveals: pygments.rb (0.2.3), rubypython (0.5.1) among others.

After running rails s -e production I see the following error in stdout. This error happens first:

Completed 500 Internal Server Error in 595ms

ActionView::Template::Error (Could not open library 'lib.so': lib.so: cannot open shared     object file: No such file or directory):
1: <% bash_lexer = Pygments::Lexer[:bash] %>
2: <div class="">
3:   <div class="git-empty">
4:     <h2>Git global setup:</h2>

`_app_views_projects_empty_html_erb___391147148_103534650'
app/controllers/projects_controller.rb:66:in `show'

then I see this:

ActionView::Template::Error (undefined method `highlight' for nil:NilClass):
7: git config --global user.email  "#{current_user.email}"
8: eos
9: %>
10:     <%= raw bash_lexer.highlight(setup_str) %>
