PlainAPM extension needs #{name} Ruby library header to compile.
If Ruby is installed from a package on your system, please ensure the
corresponding Ruby development package is installed as well.
E.g. on Debian/Ubuntu, this would be achieved by running
sudo apt install ruby-dev
on CentOS/Fedora, run
sudo yum install ruby-devel

<<-MSG
PlainAPM extension to track object allocation on a per-thread basis is
built on top of Ruby's TracePoint API.
However, the currently running Ruby version contains bugs which,
when Tracepoints are used in together with Ractors, can cause
crashes or inconsistent tracing results.
Per-thread object allocation tracing will be disabled.
If you are sure your app is not using Ractors, you can override this by
installing plain_apm with --enable-object-tracing-override flag:
gem install plain_apm -- --enable-object-tracing-override
When using bundler, you can configure it to pass this flag to the gem
install by running:
bundle config set --global build.plain_apm --enable-object-tracing-override
