MacOS – How to run GimpShop on Lion

I've just downloaded GimpShop and wanted to run it on Lion.
So I've copied the app to the Applications folder and started it.
It starts, I can see it's doing something with cache and bam.. it goes away. The only thing left is X11 window with bash prompt.
I've tried closing the X11 app and running it again… nothing.
Is there any way I could start GimpShop on Lion?

Thanks

EDIT:
There's something wrong with font caching or immediately after fonts are cached.
If I remove the font cache directory it will go through the process of caching again and will close immediately after it [or in the middle, hard to tell].
I can see few files inside. If they stay there and I will try to start GimpShop again it will close immediately.

EDIT2:
So I've followed these instructions, but I'm still getting an error:

bash-3.2$ ./Gimp

Any tips?
