Building nix from source and enabling flakes

Help
1

For various reasons (mostly having to do with being on a Mac and having FileVault enable) I want to build nix from source so that I can have an alternate nix path. I build nix just fine when its configured with ‘/configure --with-store-dir=/opt/nix/store --localstatedir=/opt/nix/var --prefix=/opt/nix’. However, the resulting binary doesn’t seem to know anything about nix flakes and I can’t seem to find any indication of it in configuration options.

Any thoughts on how to get a binary with flakes enabled such that it recoginezes the ```
experimental-features = nix-command flakes
