asterisk users - Feb 2010 - Trouble with externalIVR socket connection

I'm having trouble with ExternalIVR's socket connection.  Is it working
in the current 1.6.0 trunk?  I'm getting this error:
Executing [s at ck987_externIVR:1]
ExternalIVR("SIP/itp_jnctn-0000006c",
"ivr://127.0.0.1:9012") in new stack
[Feb 21 13:38:12] NOTICE[15864]: app_externalivr.c:631 eivr_comm:

  == Spawn extension (ck987_externIVR, s, 1) exited non-zero on
'SIP/itp_jnctn-0000006c'

Here's my Dialplan:
[ck987_externIVR]
exten => s,1,ExternalIVR(ivr://127.0.0.1:9012)
exten => s,n,Hangup()

I'm running netcat in "listen mode" in a separate shell:
[ck987 at asterisk ~]$ nc -l 9012

* I've tried the standard ivr port (2949) as well.  I was using 9012 because
I've used that port for AGI socket connections on this box so I'm pretty
sure that port is open.
* I've tried using localhost instead of 127.0.0.1
* I've tried adding "n" as an option, just in case there had to be
an option.
* I'm running Asterisk 1.6.0.20 on Linux Red Hat 4.1.2, x86_64

Before I submit a bug I want to make sure I'm not missing something.

Thanks,
Chris
