rbenv fails to install 3.3.1 on Ubuntu 24.04 because openssh builds a lib64 directory but ruby expects a lib directory

[rockorequin]

I installed ruby-build from git into ~/.rbenv/plugins/ruby-build and tried installing ruby 3.3.1 on a freshly-installed Ubuntu 24.04 VM using rbenv, but it failed due to an inability to find the openssh/lib directory (see attached log).

The issue is that openssh is building with a lib64 directory instead of a lib directory. Manually linking lib64 to lib while the ruby source tarball is being downloaded fixes the issue:

cd ~/.rbenv/versions/3.3.1/openssh
ln -s lib64 lib

rbenv build failure.txt
