OS X Lion, FileMerge will not launch [Problems]

[Dan Parent]

Hello everyone,

After moving to Lion from Snow Leopard I noticed that I could not launch filemerge for my diffs in MacHG. After emailing back and forth with Jason (not sure if that is the main developer, I'm guessing it is) I found out the problem and I have a fix that is working on my machine. Here is what happened to me and how I fixed it:

Hope this is helpful for someone else.

Thanks,
Dan

Thanks, Dan!

I hope to handle this better in the forthcoming update for MacHg for Lion issues.

Thanks,
