emacs-22.0.99 configure problem

[Hiroshi Fujishima]

I run ./configure with FreeBSD 6.2 machine.  It outputs following error:

% ./configure
as_func_failure succeeded.
as_func_failure succeeded.
No shell found that supports shell functions.
Please tell address@hidden about your system,

It seems that ./configure use /usr/local/bin/zsh...
