[R-sig-Debian] R hangs on the stats.so library

[ottorino]

Dear all,
I having this problem on my laptop.
It was caused by my clumsy attempts to upgrade the system.
As I wrote here,
(http://www.mail-archive.com/r-sig-debian@r-project.org/msg01364.html)
I was trying to solve the same problem with JAGS/rjags on my laptop.

After typing R in a terminal I'm currently get the following: 

> R version 2.9.0 (2009-04-17)
> Copyright (C) 2009 The R Foundation for Statistical Computing
> ISBN 3-900051-07-0

What I did before:

sudo nano /etc/apt/sources.list

The file sources.list contains the following lines

Then I did:

sudo apt-get update
sudo apt-get upgrade

and then a lot of clumsy commands to try to recover from the situation.
I can post them all if necessary, but basically they were:

sudo apt-get remove r-base
sudo apt-get remove r-base-core 

sudo apt-get install r-base-core 
sudo apt-get remove r-base-core r-dev
sudo apt-get install  r-base-core r-dev r-recommended 

and similar attempts.

Since I was getting some error from R I probaly worsen th situation
typing:

sudo apt-get install libmpc
sudo apt-get install r-devel
whereis libgfortran
whereis libgfortran.so.2
sudo apt-get install libgfortran3
sudo apt-get install libgfortran3-dev 
sudo apt-get install libgfortran2 
sudo apt-get install libgfortran3-dbg 
R
sudo apt-get remove  libgfortran3-dbg 
sudo apt-get install build-essential
sudo apt-get install r-base-core r-doc-info r-mathlib r-recommended 
R
sudo apt-get install r-base-dev 
sudo apt-get install f2c
R
sudo apt-get install r-base-core r-doc-info r-mathlib r-recommended 
sudo apt-get remove  r-base-core r-doc-info r-mathlib r-recommended
r-base-dev 
sudo apt-get install r-base-core r-doc-info r-mathlib r-recommended
r-base-dev 
R
sudo apt-get remove f2c
sudo apt-get install g++ gfortran
sudo apt-get autoremove

I do not exactly remember why I gave the above commands, since all the
above happened about one month ago, but I remember that the problem was
caused by libgfortran.so.2

Could please someone help me to escape from this situation ?
Thanks
