I simply wanted to mention that there is an Allegro Game Programming wiki that shows step by step how to set up Allegro to work with DMC.  I went through the steps and found them to be accurate.  It took about 5 minutes from start to finish.  Here is the url to the wiki:

And while I'm just plugging Allegro...  The book titled "Game Programming All In One" by J. Harbour is a great resource for someone learning Allegro or game programming in general.
