   I just installed mit-scheme on my ubuntu hardy hardon system. I can't 
   load the edwin editor for some reason. This is the first time I tried to 
   load it, so I manually typed "(create-editor)" on the commandline and I 
   got this respone:
    > 1 ]=> (create-editor)
    >
    > ;Can't find any usable display type
    > ;To continue, call RESTART with an option number:
    > ; (RESTART 1) => Return to read-eval-print level 1.

Judging by the config.log you sent earlier, MIT Scheme found neither
what it needs to use Xlib nor what it needs to use your local termcap
implementation.  There should be packages called something like
`x11-dev' and `ncurses-dev' (I don't know what their exact names are;
I don't use Ubuntu) that enable Scheme to do this; install those and
rebuild the microcode -- run `make clean all' in src/microcode/.

   I try loading the editor manually, by typing "edit" and this is what I get:
    > 1 ]=> edit

You need to call the EDIT procedure in order for it to do anything.
