You may want to ask on the chicken-users list (chicken-users@nongnu.org, subscribe at
https://lists.nongnu.org/mailman/listinfo/chicken-users). The current list of maintainers is at (
http://wiki.call-cc.org/maintainers), you could also contact them directly. Or on free node's #chicken
Now, the C source is not included in the repository itself, so if you are (somehow) building from that(for instance, you already have a working chicken), you are ok. They are only included in the "release tarballs".
How does your package manager get around bootstrapping compilers, in general? Guile's approach requires maintaining a one-shot interpreter/compiler in C, that's only ever used once. I don't think all projects do that.
