Correct. Not sure how that happened but Ive since deleted the files and
reinstalled. However the error persists:

    $ org-ruby -d alpha.org
    Exception `LoadError' at
    /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55 - cannot load
    such file -- coderay

I found a fix like this:

diff --git a/lib/org-ruby/html_output_buffer.rb
b/lib/org-ruby/html_output_buffer.rb
index 9d6a061..c0d5f2e 100644
--- a/lib/org-ruby/html_output_buffer.rb
+++ b/lib/org-ruby/html_output_buffer.rb
@@ -44,6 +44,7 @@ module Orgmode
         rescue LoadError
           # Pygments is not supported so we try instead with CodeRay
           begin
+            gem 'coderay'
             require 'coderay'
           rescue LoadError
             # No code syntax highlighting

However it turns out that was a red herring. The problem isnt $LOAD_PATH, the
problem is my source file:

    $ cat alpha.org
    #+BEGIN_SRC rust
    fn main() {
       println!("alpha beta");
    }
    #+END_SRC

Coderay does not support Rust currently:

https://github.com/rubychan/coderay/issues/208

If I try again with Ruby code it works fine, even without any patches:

$ cat beta.org
#+BEGIN_SRC ruby
puts 'hello world'
#+END_SRC

$ org-ruby -d beta.org
Exception `LoadError' at
/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55 - cannot load such
file -- coderay
<pre class="src" lang="ruby">
puts <span style="background-color:hsla(0,100%,50%,0.05)">
<span style="color:#710">'</span><span style="color:#D20">hello world</span>
<span style="color:#710">'
</span></span>
</pre>

Thanks for the response - sorry for the noise.
