I tried to comment out both lines and to follow the comment (leave
path empty), but that doesn't work. I had to comment out the
second line and uncomment the first one (my GTK libs are in
/usr/lib -- Debian).

After i ignored the error with drawing.lisp, the rest compiles
fine. But the demo raises an error (while showing the
splash-screen):

`----

That assertion seems to be part of the macro DEF-GTK. But
according to the source, ACTIVATE is indeed defined in
*widget-callbacks* and the REPL says the same. So I'm a bit
confused and i think my Lisp knowledge is not good enough to fully
debug this (any hints and tips are welcome).

BTW: What do those "Source: Error finding source" errors mean?
