Sil not working on some Macs

[half]

On some Macs, Sil works fine. On others, after launching it it quits immediately without bringing up a window or leaving a crash log. All of the machines I have access to work fine, but I'd love to fix this problem. Does anyone have any ideas?

If you play it on a Mac, could you let me know if it works for you, and your type of machine / version of OS X / whether you have the DevTools installed? That might help work it out, but I have to admit that I have very little knowledge of Mac-specific programming, so I will probably need some help. Perhaps this has come up in V or NPP?

The strange report about Sil appearing to have two 'main' functions on this page might lead somewhere, but when I tried testing it in gdb (on a machine where Sil works) it only showed one 'main':
