Installing Delphes in Madgraph Directory

I would like to update the issue which I posted earlier. I tried installing Delphes-3.4.2 independently using make and I could succesfully install it without any error. However, I am unable to link it with Madgraph. So I tried to install it within the MG using the command "install Delphes". But I once again face the following error :

MG5_aMC>install Delphes

Please help.

To link a local install of Delphes you just have to edit the file
input/mg5_configuration.txt
and you put a line defining delphes_path (and be sure to uncomment that line)

Cheers,

Olivier
