[R] install.packages and MacOS 10.3.8

[Patrick Giraudoux]

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)

(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' ...

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
