Thank you for contacting us.
It seems that you need to Qt5 to install gpsbabel, unfortunately this package is not include in the Intel Edison's latest image.
I’ve never tried to configure Qt5 on the Edison, but I have found a guide that was made by a community user that describes how to configure Qt5 on the Edison. I’d suggest you to take a look at http://hobby.farit.ru/qt5-gui-intel-edison/, if you have issues installing it, I recommend you to try to contact the author of the guide for further information.
I really hope that you find this guide useful, and let us know if it works.
Have a nice day.
