I'm having trouble getting up and running with blackhole. I've installed it, and when I run "bsc", I get the following prompt:

  Loaded Black Hole.
  Gambit v4.6.1

So far, so good. However, when I try to import srfi-13 (bundled with blackhole), I get this error:

> (import (std srfi/13))
*** ERROR -- Wrong number of arguments passed to procedure
(14_#char-set-adjoin!
 '#<14_#:char-set #2 14_#s: "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\...
 #\xb5)

For reference, here are the steps I've followed to install blackhole:

1) installed the blackhole/ directory in /usr/local/share/
2) put in the PATH a soft link to gsc called bsc.
3) compiled blackhole by running "gsc build" from within the blackhole directory.
4) Added the following to .gambcini:

(let ((blackhole-path "/usr/local/share/blackhole"))
          (and (equal? (path-strip-directory (car (command-line))) "bsc")
               (load (path-expand "build" blackhole-path))
               (begin
                 (set! module#ns-file (path-expand "ns.dat" blackhole-path))
                 (println "Loaded Black Hole."))))


Any suggestions would be greatly appreciated,
