---------------------------------+------------------------------------------
 After installing R-framework and R-app, within either the R command
 install.packages("rgl") yields a failure to compile:
 {{{
 In file included from Texture.hpp:14,
                  from scene.h:18,
                  from ABCLineSet.hpp:4,
                  from ABCLineSet.cpp:1:
 opengl.hpp:24:19: error: GL/gl.h: No such file or directory
 opengl.hpp:25:20: error: GL/glu.h: No such file or directory
 make: *** [ABCLineSet.o] Error 1
 ERROR: compilation failed for package ‘rgl’
 }}}

 After some googling, it turns out that after installing the port 'mesa'
 the R command succeeds in the terminal interface to R-framework, but not
 in the R-app interface:
 {{{
