If this doesn't point to something like `gcc-11`, you can remove it (if it is a symlink) and/or link the real `gcc-N`
binary to a `bin` directory that's at the head of your `$PATH`, something like:
+```shell
+ln -sf /opt/homebrew/bin/gcc-11 /usr/local/bin/gcc
+```
+or this for earlier versions of homebrew.
```shell
ln -sf /usr/local/bin/gcc-11 /usr/local/bin/gcc
```
