cr-1.9 problem with adding new extensions

Hello,

I need some help, by adding new extensions to chromium. I tried to add a 
new extension to chromium, "glCreateShader", how described in docs "Adding 
OpenGL Extensions to Chromium". I've modified the "cr_versions.h" and replace 
the "glext.h" with a new one, to support OpenGL 2.0. I've added to APIspec.
txt following strings:
name   CreateShader
return   GLuint
param  shaderType  GLenum
paramprop shaderType GL_VERTEX_SHADER GL_FRAGMENT_SHADER
category 2.0
props nolist get
chromium extpack

After it i've implemented the new code for this extension throughout Chromium.

The compilation process works fine, i got no Errors, but if i tried to launch 
an application demo i got two error messages:
1. "DLL_ERROR ../libtilesortspu.so: undefined symbol: tilesortspu_CreateShader"
2. "CR Error(Localhost:24345): DLL Loader couldn't find/open libtilesortspu.
so" 

With best regards 
Johann.
