Problem with cond macro.

[Panagiotis Vossos]

Ok, I just started studying macros, so I might be missing something
obvious, but the following example from r5rs doesn't work correctly
with guile:

guile> (version)
"1.5.6"
guile> (let ((=> #f))
         (cond (#t => 'ok)))
standard input:3:10: In expression (cond (#t => #)):
standard input:3:10: Wrong type to apply: ok
ABORT: (misc-error)

Type "(backtrace)" to get more information or "(debug)" to enter the debugger.
guile> 

SCM and s48 correctly return 'ok.  I wondered if something was wrong
with the built-in 'cond', so I defined 'my-cond' using the definition
from the last section of r5rs.  Unfortunately, the above example still
didn't work.  Any ideas?
