To install the OpenGL::Shader module, please follow these instructions:

1. Install the OpenGL module first - you need at least version 0.55 See the Perl OpenGL (POGL) Developer's Site: http://graphcomp.com/opengl
2. Run 'perl Makefile.PL'
3. Run 'make' ('nmake' on Windows).
4. Run 'make test' ('nmake test' on Windows). Note: to run this test, you must have GLUT installed, and be able to create a GL context (window).
5. If all is well, run 'sudo make install' ('nmake install' on Windows) to install OpenGL::Shader on your system.
