@winslowdibona try to fix build.sh:

docker run --rm -it -v $PWD/task:/var/task \
    -e LD_LIBRARY_PATH='/lib64:/usr/lib64:/var/runtime:/var/runtime/lib:/var/task:/var/task/lib' \
lambdalinux/baseimage-amzn /var/task/build_weasyprint.sh

You may also need to add "" "" after lib_install _package_name_ (because lib_install function requires 3 args) and add bzip2 in yum install command. Script should run then, but it doesn't work because of compilation errors :(
