[smokeping-users] Curl not reporting data

I have recently installed Smokeping and I am trying to get the curl probe to
work.  I have been running the daemon in debug mode to troubleshoot the curl
issue I am having.  It appears that the curl probe is not getting the data
that it needs and is recording 100% packet loss.

The problem is if I run the following command data gets returned as you
would expect.

[root at XNETOPS01 etc]# /usr/bin/curl -m 10 -o /dev/null -w "Time:
%{time_total} DNS time: %{time_namelookup} Redirect time:
%{time_redirect}\n" www.google.com
  % Total    % Received % Xferd  Average Speed   Time    Time     Time
                                 Dload  Upload   Total   Spent    Left

Time: 0.035 DNS time: 0.002 Redirect time: 0.000

I changed a few of the delimiting characters to be able to run it at the
command line but nothing that I can see that you change the output.  Has
anyone else had a similar problem with the curl probe and if so how did you
fix it?

Here are the versions and a config snippet


*** Probes ***

+ FPing
binary = /usr/local/sbin/fping

+ Curl
# probe-specific variables
binary = /usr/bin/curl
pings = 5
step = 60

# a default for this target-specific variable
urlformat = http://%host/

+ Curl
menu = Curl
title = Curl Probe

++ Google
menu = Google.com
title = Google.com
probe = Curl
host = www.google.com

Thanks for any help.
