hi there!
I've checked out your project, it's funny!
Though some errors I've encountered during compiling time, some header
files was missing, it's easy to fix.
Besides, I've noticed that you used Guile-1.6 for AI script, why not use
brand new Guile-2.x? It's easy too. I did this "upgrade" myself and it
works.
I think there're some deprecated Guile APIs should be changed:
------------------cut----------------
SCM_MAKINUM ==> scm_from_int
SCM_INUMP ==> scm_is_integer
SCM_INUM ==> scm_to_int
SCM_VECTORP ==> scm_is_vector
----------------cut end------------

The game is great. But there's frame skip/unsteady problem in the
beginning. I didn't find out the reason. Maybe it's the problem of
Guile-2.x, because the AI script will be compiled when it's loaded, so
there'll be some delay in the beginning of the game. Guile-1.6 is pure
interpreted, so I think it'll be OK.
I just guess. If it's the final reason, I suggest you pre-compile your AI
scripts.
