Hi there,I try arround with xnec2c in moment and have found by routine check a ticket on launchpad that has already a patch laying arround since 2010.
It is only a .desktop file to incorporate xnec2c into the system menu designed by Peter Pall. May be you are interested.
The launchpad ticket is: https://bugs.launchpad.net/ubuntu/+source/xnec2c/+bug/615616/ greetings melchiaros
