[Pw_forum] Quantum Espresso installed, but examples not running

[Alexander Eftimiades]

I hope I came to the right place to ask this question. I have compiled  
quantum espresso using this set of instructions:
http://how-to.wikia.com/wiki/How_to_install_PWscf_on_a_Debian_or_Debian_based_operating_system

I made two modifications to these instructions:
I installed version 4.2.1 and put the folder together using these  
instructions:http://qe-forge.org/frs/shownotes.php?release_id=64.  
These instructions did not say anything about "PLUMED" plugin so I did  
not download it.
I have gfortran installed so I did not do the first part of the  
instructions (although I later tried to install g95 using the link  
provided and it kept saying "authentication failed")

I have openmpi installed but I only have one cpu at the moment (I  
intend to set up a network later.)

Everything seemed to work ok so I tried to run one of the examples. I  
got this:


/opt/espresso-4.2.1/examples/example08 : starting

This example shows how to use pw.x to calculate the DOS of Ni.

Similar messages come up for other examples. Could someone please tell  
me what is going on? And--yes I read the user manual instructions (and  
yes chapter 2). If there is a pointer in there I missed please tell me.
