I have a strange issue with RVM, where I’m getting this error while attempting to install ruby 2.x:

ERROR: While executing gem … (Gem::FilePermissionError)  
You don’t have write permissions for the /opt/local/lib/ruby3.0/gems/3.0.0 directory.

It shouldn’t be trying to pull from the system/macports area. All the other commands seem to work, and for 3.1. I don’t have any local .profile variables set.

I’m not sure where to look for this one. Anyone encounter it?
