apt install make libffi-dev gcc (possible ruby-dev) may be helps you.

or try install td-agent v4 instead of the more oldest

Hi I solved this issue by uninstalling the tzinfo-2.0.0 and depending on the installed version which comes with the connector. "gem uninstall tzinfo -v 2.0.2 " in the Dockerfile

This error should be occurred from lack of building toolchain such as gcc and make.
You must install C language development tools first.
This plugin depends on pg gem which contains C extensions.
