It looks like you're trying to do some kind of graphics programming
with Guile but don't have the right libraries loaded
("filled-triangle" is not, to the best of my knowledge, part of R5RS).
Perhaps you're missing a use-modules expression?
It would be helpful to know more about what you're trying to do here.
