I'm trying to install the R package rgl on Ubuntu 9.10. I'm using R version 2.12.1.
I got the following error: "configure: error: missing required header GL/gl.h"
Edit: My original question did not specify that the operating system must be Ubuntu 9.10. I gather that otherwise it would be a good idea to update R, but that this cannot be done on Ubuntu 9.10. Because I'm stupid, I posted a new question instead of editing this one, so some discussion has occurred there.
