Hi There,
I have read a lot of other rbenv issues but nothing helped to turn around my issue.

I am using Catalina 10.15.7 with zsh and got a c compiler error

rbenv install 3.0.0                                             1 ✘  3m 57s   13:55:34  

I have installed llvm with no errors.

I am suspecting of a Kind of conflict but not sure ... my Install sequence in this environment was :

NODE 14
Python
and now ... trying Ruby on Rails ...

Any ideia ?
Best Regards
