My operating system is Debian Squeeze. Here's the vim version:
VIM - Vi IMproved 7.2 (2008 Aug 9, compiled Jul 12 2010 02:29:33)
I read a tutorial on http://kovisoft.bitbucket.org/tutorial.html and tried to start REPL for MIT-Scheme. Unfortunately, I failed to start.
When I pressed ",c", it started a terminal window loading mit-scheme. Nothing showed in the REPL buffer of vim. Some errors showed in the terminal:
Listening on port: 4005
;netcat: "4005: inverse host lookup failed: Unknown host"
;To continue, call RESTART with an option number:
; (RESTART 1) => Return to read-eval-print level 1.
2 error>
I read the source code and fixed some bugs (about the parameters of netcat and something else), here's the diff file:

I retried, but some new problems happened.

This is a known problem. I have a patched version of Slimv in my git repo which fixes this issue and quite a few others.
Note that it's quite a while ago that I used Slimv, so I can't recall from the top of my head what the exact changes are I made. I only tested this on OS X, so YMMV.
