[R] package installation

[rachid cheddadi]

Hi, 
I had R working since version 1.4. Then I bought a new HD and installed
a RH 7.3 on it and since then I can no longer install any R package. 
Here is the failure message I obtain: 

...

/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
make: *** [fields.so] Erreur 1
ERROR: compilation failed for package 'fields' 
  

I obtain the same message for any other package. I checked, I have
readline and ncurses installed. So I don't quite see where the problem
comes from. 
Any help please? 
Many thanks 
Rachid
