When I tried to run the first example of the pict3d doc

(require pict3d)
(current-pict3d-legacy? #t)
(sphere origin 1/2)

I get the following error message

get-master-gl-context: could not get at least an OpenGL 30 context (legacy? = #f)
  context...:
   /home/csvelayutham/racket/collects/racket/private/more-scheme.rkt:370:13: hash-ref!
   /home/csvelayutham/.racket/6.1.1/pkgs/pict3d/pict3d/private/gui/pict3d-snip.rkt:103:7
   /home/csvelayutham/.racket/6.1.1/pkgs/pict3d/pict3d/private/gui/pict3d-snip.rkt:91:2: render-thread-loop

After this following the document, I inserted the (current-pict3d-legacy? #t)

(require pict3d)
(current-pict3d-legacy? #t)
(sphere origin 1/2)

Still I get the following error message

get-master-gl-context: could not get at least an OpenGL 30 context (legacy? = #t)
  context...:
   /home/csvelayutham/racket/collects/racket/private/more-scheme.rkt:370:13: hash-ref!
   /home/csvelayutham/.racket/6.1.1/pkgs/pict3d/pict3d/private/gui/pict3d-snip.rkt:103:7
   /home/csvelayutham/.racket/6.1.1/pkgs/pict3d/pict3d/private/gui/pict3d-snip.rkt:91:2: render-thread-loop

Am I going wrong somewhere?
