ghostscript driver configuration dialog

[Rajat Datta]

When building ghostscript (either -afpl or -gnu) with make install, a driver 
configuration dialog pops up.  Unfortunately, I have been unable to get it to 
accept any choices I make.  That is to say, hitting the ENTER key simply 
toggles the current choice on or off, as does SPACE.  If I choose CANCEL, the 
make immediately terminates.  So how do I actually choose OK?   Ctrl-M, 
Ctrl-J all simply toggle the current choice on or off.
