dnscache runs under daemontools, unable to bind (access denied) using runit

["Charles M. Gerungan" <charles@nednieuws.com>]

This starts up dnscache and it responds to queries:

# cat run.daemontools
#!/bin/sh
exec 2>&1
exec <seed
exec envdir ./env sh -c '
   exec envuidgid Gdnscache softlimit -o250 -d "$DATALIMIT" /usr/ 
local/bin/dnscache
'

This does not start up (an adapted version of http://www.skarnet.org: 
80/lists/archive.cgi?2:msp:1046:midfmaimamejgmijfagg -- the content  
of the env dir wasn't given so I hope I interpreted the manual  
correctly):

# cat run
#!/bin/sh
exec 2>&1
exec <seed
exec chpst -v -u Gdnscache:Gnofiles -e ./env -o 250 /usr/local/bin/ 
dnscache

The error I'm getting when invoking:

# ./run
dnscache: fatal: unable to bind UDP socket: access denied

Here's the content of the env dir:

# ll env

Why am I getting the error and how do I solve it?
