[Pw_forum] Quantum Espresso installed, but examples not running

I should then mention that everything used to compile and execute  
Quantum Espresso was built for Debian because it was installed using  
synaptic package manager. The large library of packages Synaptic  
provides is exactly the reason I use Debian.
I just updated all my software recently so I am quite sure I am using  
the latest version of MPI, gfortran, etc Synaptic has to offer.

If you still think my compilers are the problem--any ideas on how I  
could go about fixing this. I scoured the web for free ab initio  
quantum chemistry software that can calculate phonon dispersion  
relations and this definitely seemed to be one of the best. I would  
really like to get this running--especially since my projects are not  
very different than some of the examples provided.
