In /etc/fstab, I have the following.
tmpfs /tmp tmpfs
defaults,size=100M,mode=1777,noexec,nosuid 0 0

Mounting /tmp with "noexec" is a security measure, since /tmp may easily become a vulnerable spot on a Linux system.

Running "R CMD INSTALL rgl" from my reiserfs / partition was enough for the ./configure script to get executed and for rgl to build properly [1]. Now I can dyn.load() rgl with no error messages, although it is somewhat crashy. I will report here if I get any meaningful error messages.

Thanks goes to all who contributed with their suggestions. Best regards,
Liviu
