I've removed the reliance on string streams as described
in my blog:

With this change and some other minor tweaks, chibi-Scheme
now builds and runs on Plan 9. Unfortunately, it crashes
after an arbitrary point, suggesting a problem with the GC.
That will be my primary focus this coming week.
Floating point numbers aren't working yet on Plan 9, either,
printing out incorrect results. I haven't looked into this
yet.
Once these bugs are out of the way, I'm going to start on
providing a 9p interface.
If anyone is interested in playing with it, I've made the
mercurial repo available at
http://code.google.com/p/chibi-scheme/
