Installing Intel Fortran on debian - db3 errors ?

[B Thomas <thomas.1037@osu.edu>]

Hi,
I am trying to install intel fortran 90 compiler on debian unstable.
I get the following error :

error: cannot open Packages index using db3 - No such file or directory (2)
error: cannot open Packages database in /var/lib/rpm
Installation failed.

I would be greatfull if you could give me a pointer on what may be
wrong and if it is possible to install these rpm packages on debian.
I am not familiar with rpm but know dpkg and alien well.

Please note I am using the free (i.e. "free for personal use") version
of intel compilers.
