Hello

To update from R 2.6 to 2.8 (on Ubuntu 8.04 both) I had to install new tcl and liblapack packages (excuse me it is in french):

 sudo apt-get install r-base-dev
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances Lecture des informations d'état... Fait
Les paquets supplémentaires suivants seront installés :
  libblas-dev liblapack-dev r-base-core tcl8.5 tk8.5
Paquets suggérés :
  cdbs
Les paquets suivants seront ENLEVÉS :
  refblas3-dev
Les NOUVEAUX paquets suivants seront installés :
  libblas-dev liblapack-dev tcl8.5 tk8.5
Les paquets suivants seront mis à jour :
  r-base-core r-base-dev
2 mis à jour, 4 nouvellement installés, 1 à enlever et 19 non mis à jour.
It installed libblas-dev liblapack-dev and removed refblas3-dev.

I'm now unable to run the Matrix library, whatever I install it from within R or with apt-get, it claims a problem:

library(Matrix)
Loading required package: lattice
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared library '/usr/lib/R/site-library/Matrix/libs/Matrix.so':
  libRlapack.so: cannot open shared object file: No such file or directory
Error: package/namespace load failed for 'Matrix'

but there is a file Natrix.so in this directory (but no libRlapack.so)

Do you see where the problem is? Was I right to update R in this manner?

Thanks!

Matthieu
