SorThanks for the reply!!!.ry for my being so lazy and thanks a lot for your 
kind replies.....

 Well, I tried to install GDD  under freebsd (this time I read cafrefully the 
package docs and checked if the required libgd and 
freetype2 were installed and they were) BUT there's 
something wrong with  "Makevars":


NbBSD# R CMD INSTALL GDD_0.1-8.tar.gz
