I suspect I am missing something obvious but I have not been able to
get the sample implementation of SRFI 150 to run.  With Chibi, I get
the following error message when I 'make' with the Makefile in the repo:

  ERROR on line 29 of file ./srfi/147.scm: too few ...'s

A fuller transcript is below. For reference, output of "chibi-scheme -V":

  chibi-scheme 0.8.0 "oxygen" (chibi r7rs ratios complex threads
  full-unicode modules dynamic-loading linux little-endian)

I also tried with Kawa and Larceny without success.  Kawa gives a
stack overflow and Larceny churns for about 2 minutes before a message
of the form.

    Syntax violation: syntax-case
    Repeated pattern variable
    Subform: quote

I haven't looked at the SRFI 150 implementation in detail so it is
very likely I am missing something obvious but since it's close to the
"last call" target time, I'm posting what I have for now.
