w3c checklink: problem regarding LWP::Authen::Ntlm module

Dear Sir/Madam:
 
We are working on the w3c: checklink.pl for our school project on web
caching.
Our web site URL: http://dcm.cl.uh.edu/capf3gp7/
<http://dcm.cl.uh.edu/capf3gp7/> 
 
We are getting errors for those web page links that needs authentication
(using username and password).
We are including all the error report below. 
 
We have all modules available on our machine, including the
LWP::Authen::Ntlm
module. 
 
We have downloaded the source code (Revision
<http://dev.w3.org/cvsweb/validator/httpd/cgi-bin/checklink.pl?rev=3.6.2.20&
content-type=text/x-cvsweb-markup> 3.6.2.20 ) from your website. We are
running this program from the command line. Could you suggest solution to
this problem. 
 
Your help is highly appreciated.
 
 
Following are the errors we received.
