Thanks for your inputs George and Simon. Yes I did type I as in I-Robot instead of ell. Ok, this is what I have:

apt-cache policy liblapack3gf gives
liblapack3gf:
  Installed: 3.3.1-1
  Candidate: 3.3.1-1

apt-cache policy libblas3gf gives
libblas3gf:
  Installed: 1.2.20110419-2
  Candidate: 1.2.20110419-2

and now I locate libblas:
locate libblas
/etc/alternatives/libblas.so.3gf
/usr/lib/libblas
/usr/lib/libblas.so.3gf
/usr/lib/atlas-base/atlas/libblas.so.3gf
/usr/lib/atlas-base/atlas/libblas.so.3gf.0

Simon, I do not have libblas.a and libblas.so as you wrote in your last post that I should.

Now I do not make reference to ATLAS. So I modified my .bashrc as follows:
cat $HOME/.bashrc
export LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/:/usr/lib/libblas/
export LIBRARY_PATH=/usr/lib/i386-linux-gnu/:/usr/lib/libblas/

and I see the folder /usr/lib/libblas has the following files:
libblas.so.3gf and libblas.so.3gf.0

and echo $LIBRARY_PATH gives
/usr/lib/i386-linux-gnu/:/usr/lib/libblas/

Then on compiling:

gnatmake *.adb -largs -Wl,-v -lblas
gnatbind -x example1.ali
gnatlink example1.ali -Wl,-v -lblas
collect2 version 4.4.6 (i386 Linux/ELF)

/usr/bin/ld: cannot find -lblas
collect2: ld returned 1 exit status
gnatlink: error when calling /usr/bin/gcc-4.4

So what should I do next?

Should I uninstall ATLAS completely? Is the following a neat uninstall? :

apt-get autoremove libatlas3gf-base 

Thanks.
