[Paraview] gpu_shader4 extension is not supported

[Patrick Begou]

Yes Burlen,  this is exactly what I try to do:
- one build for the nodes whitout GUI as they have no windowing system nor GPU 
(I build this using the wiki documentation)
- one build for the front end with GUI: it has no GPU but a windowing system 
(this is the blocking point at this time)
- one build on the users workstations where a GPU and a windowing system are 
available (this is working too thanks to the wiki documentation)

On the front-end I have a system libGL but too old for Paraview 5 and it is 
requested by other commercial softwares. This is why I try to build a new mesa 
from sources for Paraview. I use the module environment then to set the 
LD_LIBRARY_PATH and PATH order to reach the right libraries and, as strace show, 
it seams to work fine. So I suppose it is a mesa configuration mistake in my build.

May be should I post on the Mesa forum ?
