The vim-core ebuilds have a line: addwrite /dev/pty/* to fix a sandbox violation. This doesn't work if logged in remotely (I'm using ssh) because we are then not using the /dev/pty devices but instead are using the /dev/vc devices. Why is the VIM install dicking with the tty? Maybe that's the real problem.
try adding rw permissions on the devices. chmod 666 /dev/vc, and try again please.
I'm having the same Access Violation emerging vim-core from an Xterm: chmod: /dev/pty/s1 Also tried adding the addwrite statement and chmodding /dev/pty, but didn't work either. Can emerge from console.
