Have you tried setting the no_proxy environment variable?  It takes a comma 
separated list of domains for which proxy should not be used.  Something like 
this in the environment could work:

http_proxy=http://your.proxy.server/
https_proxy=http://your.proxy.server/
ftp_proxy=http://your.proxy.server/
no_proxy=your.intranet.domain

See the LWP::UserAgent documentation for env_proxy() for more information.

That has been implemented in the CVS version of the link checker and will be 
in the next release.  The name of the option to do that is --exclude, CVS is 
available at http://dev.w3.org/cvsweb/perl/modules/W3C/LinkChecker/

There's a related RFE which would require that too filed as 
http://www.w3.org/Bugs/Public/show_bug.cgi?id=382 , no ETA for implementation 
at the moment.

grep's -A and -B options could help a bit with that.
