Thank you. I mistakenly looked only in /usr/bin.

Fixed...  This means that G-F-R-P was correct all along: because pwd is
a runnable program, we don't need to specify :FORCE-SHELL for Unix
variants.  Because the Windows command is a string, instead of a list,
we don't have to force a shell.

And there's /bin/pwd on Mac OS X, too.
