I tried removing all those files. I only have .bashrc and .bash_profile, and renamed those to basic and bash_profile, just so they don’t get loaded, but I still get *almost* the same behavior. The only change is that, now, the terminal.app doesn’t load the $PATH correctly, so it can’t even find xmgrace. But if I try xeyes, I get the same behavior:

$ xeyes
Error: Can't open display:

:-(
