You're probably using 'su -' to get to root, right?
Two quick fixes: one, just use 'su' so that it keeps the original user's
environment. Two, explicitly set your display to whatever it's normally
set to for your users in root's .bashrc or .profile.
Not having the display set can cause an amazing variety of errors,
depending on the application. Don't worry about debugging the
tk_patchLevel thing until you know that your display is set properly.
