Log says about chicken-4.5.0, which is removed from tree. Also neither me, nor Erik Falor, new proxy-maintainer of chicken, have never seen this message. Can you explain how and why it appears?
you can find the relevant information from here:
Basically you add –Wl,–hash-style=gnu to your LDFLAGS which portage will check for in the final binaries.
chicken-4.8.0 should respect them. I'll keep this open until we stabilize it and remove the previous.
chicken 18.104.22.168 is stable.
