The package was built via Python-QT, which in theory should run unmodified on the N9, now I don't exactly know if zenity is available for Harmatan, but lets just see if the main UI boots or not. I'll figure something out later for file selection.
So to start, you should be sure that you've got python2.5-qt4 installed (not sure of the version numbers in harmattan), then extract the contents of TEST.zip to a known folder in your N9/50, then simply:

Code:

root (AFAIK N9 users do openshh so I don't exactly know, just get root permissions)

python /path/where/the/folder/is/Build_me.py

Post your findings!
