Uh yeah. dead end.

I use which.el, myself, which is fast. However, I recall that there
is some which()-like emacs function.

Don't know of symlink; the release version is not out yet.

zsh is not posix/xpg4 compliant, but does a good job of running
every ksh/bash command you throw at it.

You are probably right; most modern unixes should have at least
ksh-88 (original old Korn Shell) installed. Except Mac OS-X.
However, zsh is pretty much ksh-88 compliant.
You could probably do
/bin/ksh || /bin/zsh
and hope that these are the correct directories.
