That complaint is in the context of the default config that handles 
requests Apache can't determine as being for any virtual host. Not a 
serious problem, since you don't really want that config catching 
anything, I assume...

So, Apache httpd is seeing the config file for the RT virtual host. 
That's good.

At which point I have to ask what may seem like an insulting question 
but really it isn't meant as such:

Are you restarting Apache after every config change?

Because while "httpd -S" will parse your current config files and tell 
you what Apache httpd would do if it was using those files, the live 
httpd processes are always using whatever config was parsed and loaded 
when their master process (assuming you're using the pre-fork MPM) was 
started.

Don't do that. Or if you do, remove the VirtualHost "tags" around the 
config for RT. You DO NOT want the default host config for Apache 
handling requests for RT if you have RT configured inside a virtual host 
section. If you tell the default config its name is 
rt-ir-sandbox.snip.snip.snip.edu, it will handle requests for 
rt-ir-sandbox.snip.snip.snip.edu.

Since httpd -S is picking up your rt.conf file, that Include directive 
is correct.

The only other thing that comes to mind is the actual RT config in 
/opt/rt4/RT_SiteConfig.pm. If you haven't set WebDomain to 
rt-ir-sandbox.snip.snip.snip.edu, RT might (not sure off the top of my 
head...) redirect requests to use its default WebDomain, localhost", and 
if you're testing with a browser on the host itself that'll still work 
but hit the default config.
