BusyBox’s implementation of Awk does not work

[KrzysiekJ]

Steps to reproduce (using Docker):

docker run -it --rm alpine:3.7

Inside the container:

apk update
apk add git make
git clone https://github.com/nuex/zodiac.git --depth 1
cd zodiac
make install
cd example
make

The error which occurs is:

zod site www
awk: bad regex '{{{yield}}}': Repetition not preceded by valid expression
awk: bad regex '{{{yield}}}': Repetition not preceded by valid expression
awk: bad regex '{{{yield}}}': Repetition not preceded by valid expression

apk add gawk fixes the problem. According to GNU’s manual on Awk implementations, “BusyBox […] includes a full implementation of POSIX awk.”.

I can't help, but I can tell that zodiak works fine on the posix awk implementations on FreeBSD and OpenBSD. Maybe something is missing in the busybox awk. I don't need gawk here.
