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
* Installing *source* package 'GDD' ...
checking for gcc... cc

checking for cc option to accept ANSI C... none needed checking how to run the C preprocessor... cc -E checking for egrep... grep -E

checking for gdlib-config... /usr/local/bin/gdlib-config libgd-flags according to gdlib-config:

   -I/usr/local/include -L/usr/local/lib -L/usr/local/lib -lgd if that is not correct, fix your gd installation checking gd.h usability... yes
checking gd.h presence... yes
checking for gd.h... yes
checking for gdImageCreateFromPng in -lgd... yes checking usability of FreeType in GD... yes checking whether GD programs can be compiled... yes configure: creating ./config.status
config.status: creating src/Makevars
config.status: creating src/gddconfig.h
** libs
"Makevars", line 2: Need an operator
"Makevars", line 4: Need an operator
make: fatal errors encountered -- cannot continue chmod: /usr/local/lib/R/library/GDD/libs/*: No such file or directory ERROR: compilation failed for package 'GDD' ** Removing '/usr/local/lib/R/library/GDD'

What should I do?
