--- Regarding Chicken Scheme
Ah, as far as Allegro goes in Chicken Scheme (5)
Change the use on line 3 to import.
Changing line 62 here to have (exit 0) instead of (quit 0) seems to close the window properly.
it's a start I think I can make this work...
--- Regarding Chickadee in Guile:
I tried my best installing Guile from source (seems to have gone OK) but the last mile on the two Chickadee libraries was tough.
Manged to get the .so files installed and the required Guile GL and SDL2 bindings installed, but it ended in failure when libturbojpeg couldn't be found despite me installing it.
Trace below from building Chickadee. After grabbing bindings and installing system libraries.
