XML Base Path - Google Webmaster Tools 301 Redirect Error

I just installed Drupal in a sub directory on my website to use as a Blog. http://www.danfinney.com/blog/

Everything is running and working well. I submitted the XML feed url to Google Webmaster tools as a Sitemap. Google successfully downloaded the feed but tossed the following warning:

URLs not followed
When we tested a sample of URLs from your Sitemap, we found that some URLs redirect to other locations. We recommend that your Sitemap contain URLs that point to the final destination (the redirect target) instead of redirecting to another URL.

HTTP Error: 301 (Moved permanently)
URL: http://www.danfinney.com/blog

I did some investigating and figured out what the problem was. The feed url http://www.danfinney.com/blog/rss.xml is indicating the base path of the site without the trailing slash:

alternateURL="http://www.danfinney.com/blog"
base href="http://www.danfinney.com/blog"

When you go to: http://www.danfinney.com/blog it redirects you to include the trailing slash: http://www.danfinney.com/blog/

I am using the Global Redirect module, but the "remove trailing slash" feature does not seem to work on the main directory.

I also tried to edit settings.php so that the feed would include the trailing slash in the urls, but my attempts were not successful.

I either need to change the base path to include the trailing slash, or I need the trailing slash removed. Can someone point me in the right direction?
