[R-br] Instalar pacote rgl

[Andre Oliveira]

Pessoal é uma coisa simples, mas depois de esgotar minhas pesquisas resolvi postar na lista. Coloquei o Ubuntu 14.04 aqui e resolvi instalar o Rcmdr instalou, mas requer o pacote rgl que nunca consigo instalar o mesmo. Olha minhas tentativas

Esta ali uma mensagem de erro comum nas duas tentativas X11. Suspeitei que devo instalar algum pacote no linux para resolver. Alguém tem alguma dica?
