I have a legacy application that uses ruby 2.1.0 and
$ rbenv install 2.1.0
worked fine in BigSur.

However after updating to MacOS 14.4.1 Sonoma from Big Sur 11 I can’t get it to work.
I’ve replaced the old rbenv version with a clean git install with to success

$ rbenv -v
rbenv 1.2.0-87-ge8b7a27

I’ve installed the XCode command tools after upgrading to Sonoma.
I’m using MacPorts, and I’ve reinstalled all my ports as per their instructions.

It appears that it fails to configure for x86_64, and continues with i386.

Can you please help my out on how to install ruby 2.1.0 using rbenv?
Best,
