[STATSGRASS] problem installing spgrass6 with R 2.5.1

[Mauricio Zambrano]

Thanks, but I tried several times with update.packages() and the
problem still persisted.

I uninstall R and all the installed packages and I re-installed only:

-) r-base,
-) r-recommended
-) r-base-dev

Then I did update.packages() and again I tried to install SPGRASS6 with:

> install.packages("spgrass6", dependencies=TRUE)

but again it was impossible and the next screen appeared:

Aviso en install.packages("spgrass6", dependencies = TRUE) :

Warning message:

Do somebody know if the problem is with the 'lib' parameter or it
could be anything else ?

Thanks
