Olá senhores de novo. Estou com problemas há alguns dias ao instalar pacotes que dependem do "rgl". Este pacote ("rgl") não está instalando de jeito nenhum. Já tentei até via terminal (R CMD blbaalb) e nada. As mensagens são: * installing to library ‘/home/allaman/R/i486-pc-linux-gnu-library/2.10’ * installing *source* package ‘rgl’ ... checking for gcc... gcc -std=gnu99 checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc -std=gnu99 accepts -g... yes checking for gcc -std=gnu99 option to accept ISO C89... none needed checking how to run the C preprocessor... gcc -std=gnu99 -E checking for gcc...
