Alpine is not using glibc as default library so you need to other precompiled components:
Alpine x86_64 3.7.0 - replace in "imports/linux/x64"
CentOS 6 is using old glibc, you need atleast 2.7 to start precompiled components.
Start as root to update glibc to 2.7:
wget https://gist.githubusercontent.com/harv/f86690fcad94f655906ee9e37c85b174/raw/2cfcc7922b0c2f391afb957fd209a1f1f2f9f659/glibc-2.17_centos6.sh && chmod +x glibc-2.17_centos6.sh && ./glibc-2.17_centos6.shsphinx requires openssl-1.1 which is not installed by default on minimal arch installs
pacman -S openssl-1.1
