OSX App wont run on other machines

[December]

Hi All,

I used this script ( http://qtnode.net/wiki/Distributing_Mac_Qt_applications ) to create a disk image of a small app I wrote. It uses QtGui, QtCore, QtXml and QtNetwork.

The script gave no errors during the process and made a .dmg file

When I test the program on the development machine it works fine.

When I try on another almost identical mac, an icon shows in the dock for a few seconds and then it disappears.. no errors, no windows.. nothing.

Sorry if this is a dumb questions, but where do I go from here? I'm very new to programming on OSX. The program works great under Linux (where I first wrote it) and I really want to make a mac version :-(

Thanks in advance.
