LÖVE

I'm trying to package my game for OSX (from a Windows machine, my friend is testing on his laptop remotely) and having some issues.

This error message occurs when my friend attempts to run the app: (some irrelevant lines omitted)

Any help much appreciated, I'd really like to have an easily playable build of our game jam game for my Mac-loving pals! LOVE is a great little game jam weapon.
Apologies if there are answers elsewhere on the forums, I couldn't get the search to work (tried 'mac' 'osx' and 'mpg.123', none of which returned results).

I think what's happening is that Windows destroys the symlinks or file permissions used in OS X framework folders, for example BAWSPA.app/Contents/Frameworks/mpg123.framework/mpg123 should point to mpg123.framework/Versions/A/mpg123, but it doesn't with your .app.

I'm not sure how to fix it aside from using OS X (or maybe Linux?) to modify / zip the .app - perhaps someone more knowledgable than me can jump in.

Thanks for that idea, I'll get my friend with a Mac to try packaging it and see if that works.
