Looks OK to me.

Nothing wrong with that either.

Obviously your scale is not set, which is the message 'scale set to 
1:NaN'. I would suppose that ps.map can deal with decimal inches, but if 
this is not the case this might be the cause of your problem. You could 
try if the program works with integer numbers, or set the scale to page 
width minus margins, or see if a ratio scaling works; if so, the problem 
is with the inches. Good luck!
