It is odd that the problem occurs on all machines without development tools. What's the deployment target of the application? You can check the actual deployment target in binaries (such as _AppKit.so) using "otool -vl FILENAME", look for 'LC_VERSION_MIN_MACOSX'. Having a too high deployment target could explain why the app doesn't work on 10.7, but not why it doesn't work on 10.8 machines without devtools.
