Dear sage-devel,
In trying to get R to work as well as possible when it comes to
additional packages, I notice that one problem is that on some systems
certain libraries or headers (I'm not using those terms correctly,
probably) are available, and on others not. Here is a snippet of an
example with package 'rgl', which is needed for package 'depth':
checking GL/gl.h usability... no
checking GL/gl.h presence... no
checking for GL/gl.h... no
checking GL/glu.h usability... no
checking GL/glu.h presence... no
checking for GL/glu.h... no
configure: error: missing required header GL/gl.h
This was on boxen.math (and occurred on sage.math before it bit the
dust). However, on my Macintel 10.5, it seems to install fine.
Apparently this has to do with OpenGL graphics support already being
on a machine, though I'm not 100% sure.
On sage.math OpenGL was available (all of mesa was installed), but
not in boxen.math.
