Just a few minutes ago, I aquired the code to a project that uses Allegro... I downloaded the development files from Synaptic, but I cant figure out the command to link to allegro... my experiance linking is rather limited, so its not suprising that I cant figure it out. How do I link to Allegro?

The lib name appears to be alleg, not allegro.
By the way, a quick check of the files shown here (http://packages.ubuntu.com/gutsy/i386/liballegro4.2-dev/filelist) shows a program called allegro-config. Try this command:
$ allegro-config --libs
to see if it gives the correct options for linking the library.

It returned:
-L/usr/lib -lalleg-4.2.0 -lm -lpthread -lXxf86vm -lXcursor -lXpm -lXext -lX11 -ldl
... erm, what does that mean?
Edit:
Ok, that string it returned seems to link it properly... But I assume it to be excess?

Those are all the options required to link the allegro library. For example, if you have a single file, say main.c (or main.cpp if C++) that uses allegro, and you have already compiled it to main.o, then to link you would do something like this:
$ gcc main.o `allegro-config --libs` -o main
By putting the command in back-quotes like that, the shell will replace the command with its output. You could also do it this way:
$ gcc main.o $(allegro-config --libs) -o main
