[mew-int 2204] make client process failed, connection refused

[CHENG Gao]

I am trying to use Mew. But I always get error message:
,----
| make client process failed, connection refused
`----

My environment:
Emacs 23 under MacOSX (built with ./make-package from latest cvs)
Mew CVS (latest)

I set mewe-rc-file to ~/.emacs.d/.mew.el, in which there is
only mew-conf-alist setting for one pop account.

Anybody helps me?

TIA!
