Trouble instaling WP – adds :83 to domain

So, I’m trying to install wordpress, and it looks like the installation has gone through, but I can’t get the site to work.

Here’s the site:
http://www.engr.wisc.edu/studentorgs/triangle/wordpress/
Which looks weird, as if it can’t load any of the CSS or anything.

So I noticed all of the internal links start with
http://www.engr.wisc.edu:83
instead of http://www.engr.wisc.edu

When I load a page without the port number, it loads fine, but still looks odd.
I tried adding these two lines to wp-config.php:

define('WP_SITEURL', 'http://www.engr.wisc.edu/studentorgs/triangle/wordpress/');
define('WP_HOME', 'http://www.engr.wisc.edu/studentorgs/triangle/wordpress/');

With those lines in, it not only doesn’t load but Firefox complains that the page isn’t redirecting properly. I dont’ understand: where is all this redirecting happening? Is this an issue with our server?
