That typically happens when the scheme interpreter version is not the
right one.  What versions of Racket and Geiser are you using? You can
also try M-x run-racket to make sure that you're starting Racket.

No, those functions are not part of Geiser, and you shouldn't be using
them (they're part of the standar emacs support for scheme that Geiser
supersedes, and won't work for a REPL started by Geiser).  Once you get
Geiser up and running, there are replacements for them that you can use.

That seems to be the problem, yes.  But i don't know how ob-scheme.el
works, so i'm not totally sure.  At any rate, if you cannot start a
Geiser REPL, it's almost for sure *not* ob-scheme's fault.

Cheers,
