In addition to what mario said, I want to raise these questions:

Did you build chicken from git? If so did you build a boot-chicken
and used that to build the real chicken? It would go like this
(without your customisations):

make PLATFORM=linux boot-chicken
make PLATFORM=linux CHICKEN=./chicken-boot
make PLATFORM=linux install

If you do this, does that help?

Also is it possible that you have older extensions installed on the
machine?

Kind regards,

Christian
