problem with gnats aliases and exim

[Lee Bradshaw <lee@sectionIV.com>]

gnats Version: 3.113-10
exim  Version: 3.12-7

exim doesn't seem to work with the gnats aliases:

  freefall ~ $ send-pr
  a)bort, e)dit or s)end? s
  send-pr: problem report sent
  freefall ~ $ 2000-04-21 16:27:32 12ik1U-0001bx-00 Neither the
  system_aliases director nor the address_pipe transport set a uid
  for local delivery of | /usr/lib/gnats/queue-pr -q

from /etc/aliases:

  # begin gnats aliases
  gnats-admin:    gnats
  bugs:           "| /usr/lib/gnats/queue-pr -q"
  query-pr:       "| /usr/lib/gnats/mail-query"
  freefall-gnats:    bugs
  # end gnats aliases

The sections of /etc/exim.conf mentioned in the error message:

  system_aliases:
    driver = aliasfile
  # >> Option added by convert4r3
    file_transport = address_file
  # >> Option added by convert4r3
    pipe_transport = address_pipe
    file = /etc/aliases
    search_type = lsearch
  # user = list
  # Uncomment the above line if you are running smartlist
  
  address_pipe:
    driver = pipe
    return_output

Any suggestions?
