Description

When I try to install Ruby on RHEL (8/9) with ASDF, then yum and dnf note that there is no longer a package called libyaml-devel.

In recent versions of RHEL, the package is hidden by default. RHEL users will need to explicitly enable some package groups:

# RHEL 8 based distros:
dnf config-manager --set-enabled powertools

# RHEL 9 based distros:
dnf config-manager --set-enabled crb

dnf install libyaml-devel

Per https://github.com/rvm/rvm/issues/5288#issuecomment-1387705721

For comparison, RVM uses Ruby's built-in libyaml implementation:

Also, the GCC version is out of date.

This issue appears to be specific to the underlying rbenv/ruby-build system:

Contributor guide

Research direction
Test the installation commands on RHEL 8 and 9 to confirm the need for enabling powertools or crb repos, and verify if the GCC version note is still relevant. Update the documentation accordingly.
