[R] rgdal package -- Error in installing package

[Luis Ridao Cruz]

R-help,

I'm trying to install the rgdal package under Ubuntu
but I get the following warning:


> install.packages("rgdal")
Warning in install.packages("rgdal", configure.args = "--with-gdal-modules=/usr/local/lib") :
  argument 'lib' is missing: using '/home/luisridaocruz/R/x86_64-pc-linux-gnu-library/2.8'

which causes the error:

> library("rgdal")
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared library '/home/luisridaocruz/R/x86_64-pc-linux-gnu-library/2.8/rgdal/libs/rgdal.so':
  libgdal.so.1: cannot open shared object file: No such file or directory
Error: package/namespace load failed for 'rgdal'

If I try the following:

> install.packages("rgdal",configure.args="--with-gdal-modules=/usr/local/lib")
Warning in install.packages("rgdal", configure.args = "--with-gdal-modules=/usr/local/lib") :
  argument 'lib' is missing: using '/home/luisridaocruz/R/x86_64-pc-linux-gnu-library/2.8'
trying URL 'http://cran.ii.uib.no/src/contrib/rgdal_0.6-8.tar.gz'
Content type 'ap
.....
....

Then the same error occurs and by doing:

> install.packages("rgdal",configure.args="--with-gdal-modules=/usr/local/lib",lib="/usr/local/lib")
Warning in install.packages("rgdal", configure.args = "--with-gdal-modules=/usr/local/lib",  :
  'lib = "/usr/local/lib"' is not writable
Error in install.packages("rgdal", configure.args = "--with-gdal-modules=/usr/local/lib",  : 
  unable to install packages

Can anyone helps?
