setup Smartlist with Postfix - alias config problem

I am setting up Smartlist with Postfix, and put in /etc/aliases a line =

like:

  myteam:  "|exec /home/smartlist/.bin/flist myteam"

the test mail gets bounced with this error: cannot open input.
    Command output: flist: Can't find ".etc" in "/"

Why it's looking for ".etc" under "/"?  I do have /home/smartlist/.etc/ =

that's parallel to /home/smartlist/.bin/, and everything in ~smartlist =

account looks identical to my old smartlists. I wonder if it's a wrong =

error or something is broken somewhere?
