install.packages and MacOS 10.3.8

Dear Listers,

I am trying to install packages via install.packages() from MacOS 
10.3.8. Installing work fine when run from the menu, but the following 
command (useful for setting up each computer of the student computer 
room)  leads nowhere for some reasons:

pack<-c("ade4","adehabitat","geoR","gstat","KernSmooth","lattice","leaps")
install.packages(pack,dependencies=T)

trying URL `http://cran.r-project.org/src/contrib/PACKAGES'

also installing the dependencies 'SparseM', 'gee', 'waveslim', 'splancs', 'maptools', 
'spdep', 'pixmap', 'ape', 'tripack'

(etc....)

* Installing *source* package 'SparseM' ...
** libs
/Library/Frameworks/R.framework/Resources/bin/SHLIB: line 1: make: command not 
found
ERROR: compilation failed for package 'SparseM'
* Installing *source* package 'gee' ...
** libs

etc...


Can anybody tell me what goes wrong with this command (which usually 
work without any problem with R 2.0.1 and Windows XP).

Thanks in advance,

Patrick
