xmlrpc info

[sussurro at happypacket.net (Sussurro)]

Hello,
  I have tried to sort through the code to find an answer to this, but I
wasn't able to figure it out.  When running the xmlrpc plugin from
msfconsole, I have had a lot of success with calling remote functions. The
"module.compatible_payloads" function has been giving me trouble.  When
running from the msfrpc client directly with this syntax:

> >
rpc.call("module.compatible_payloads","windows/browser/ms03_020_ie_objecttype")

I get a fault exception, which corresponds to this traffc which I sniffed
between the client and server:

<?xml version="1.0"
?><methodResponse><fault><value><struct><member><name>faultCode</name><value><i4>2</i4></value></member><member><name>faultString</name><value><string>Uncaught
exception undefined method `compatible_payloads' for
#&lt;Class:0xb6fd4ac4&gt; in method
module.compatible_payloads</string></value></member></struct></value></fault></methodResponse>

I am running ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux] with latest
svn checkout of metasploit.

Has anyone seen this problem before, and if so, are there any proposed
solutions ?

Thanks in advance for any insight.
