Hi All,

Hoping someone can help me with this. I have installed the Oniguruma gem  
by compiling from source and then installing the gem based on the  
instructions here:

[http://www.goodbyehelicopter.com/2008/02/20/install-oniguruma-on-os-x/](http://www.goodbyehelicopter.com/2008/02/20/install-oniguruma-on-os-x/)

My environment is mac osx leopard running ruby 1.8.6 and rails 2.3.4.

I can now run the following irb session successfully:

irb(main):001:0\> require ‘rubygems’  
=\> true  
irb(main):002:0\> require ‘oniguruma’  
=\> true  
irb(main):003:0\> require ‘uv’  
=\> true  
irb(main):006:0\> result = Uv.parse( “.thing {background-color: red}”,  
“xhtml”, “css”, true, “amy”)  
=\> “\<pre class="amy"\>\<span class="line-numbers"\> 1 \<span  
class="TagAttribute"\>\<span class="Punctuation"\>.thing  
\<span class="Punctuation"\>{\<span  
class="LibraryClassType"\>background-color\<span  
class="Punctuation"\>: \<span  
class="LibraryConstant"\>red\<span  
class="Punctuation"\>}\n”  
irb(main):007:0\>

Then I vendored the gem using rake gems:unpack:dependencies.

Then when starting the server or running a console in dev mode, when  
requiring ultraviolet I get the following error:

Loading development environment (Rails 2.3.4)  
irb: warn: can’t alias context from irb\_context.

I can see that oregexp.c is under vendor → gems → oniguruma-1.1.0 →   
ext but not quite sure what the custom require is missing to load the  
gem.

Has anyone seen this before or some advice if it looks like a standard  
or fixable error? It seems to rather be a rails thing, since I can load  
the gem from an irb session properly.

Would really appreciate any help …

Best

Matt

Did you run

rake gems:build

to build native extensions for vendored gems?
