I'm having a hard time installing OpenGL
Technically, OpenGL is just a specification implemented by your graphics driver. There is no such thing as an OpenGL SDK library. There just libGL.so comes with your driver. To use it, you need bindings for your programming language of choice. If it is C, "bindings" consist only of header files. However, you probably also want to use the OpenGL extensions, which are easiest to use with GLEW.
Therefore, I suggest you install the GLEW development files, all other dependencies (including OpenGL headers) will be pulled in by the package manager:
apt-get install libglew1.5-dev
