My first guess would be that you might have accidentally corrupted part of your DF install on your home computer. Bus errors will show up when the code attempts to reference stored information that has since been moved or stored in an invalid location, so redownloading and reinstalling DF would be my first thought at a solution.
Other then that the only things that come to my mind immediately are that part of your home operating system that controls memory has been messed with, though you should probably wait to see if anybody else has a better answer before you go reinstalling mountain lion and XQuartz.
Hey! Thank you for your answers... and well... I've tried reinstalling DF over and over again with no luck. I did reinstall XQuartz again without success and I was considering reinstalling Mountain Lion but argh... If I'm doing that then I was thinking on doing a clean install of it but that's such a pain... anyway I'll keep it as my last resource.
This happens to me when I run df from a relative path, e.g. ./stuff/df/df. Go into Terminal, cd into the df directory (you might type cd and drag the folder onto the window), and run ./df. If that doesn't work, ~/path/to/df/df will.
Just double-clicking on the df script should also work.
Well I've tried running it from terminal, with the df script and nothing works... :0(
DF might not be compatible with Mountain Lion yet. Your problems sound like bug 0006011.
You could try running the Windows version using Wine.
Hmmm... by the looks of it, yes... it seems I have the exact same problem there! I'll keep an eye on that thread. The problem is, I tried joining the Mantis Bug Reporting platform but I never received my registration confirmation so I can't post anything there... (someone wants me not to play this game, huh?) And yes, I'm currently using Crossover as my backup and it works perfectly.
Anyway, thank you for comments and I hope someone comes up with a solution to this. I'm just shocked that I can run it fine on my office's computer but not at home's... (and they want me to be productive at work... ha!)
