Note that to reproduce it, you must *not* have any shells installed
that the configure script classifies as "definitely usable". In
particular, if you've got bash installed (and a number of ports will
install it for you), the configure script finds that and will use
it. Also, doing things through ports causes SHELL to be set to /bin/sh
(normally, anway), and hence masks the problem.
There seem to be a fwe things in my environment specific to zsh -
other than all the completion stuff, of course, which shouldn't make
any difference - MULTIOS, zsh, FPATH and extendedglob. Turning them
all off doesn't make any difference.
Thanks,
