### 

- [X] I ran `brew update` and am still able to reproduce my issue.
- [X] I have resolved all warnings from `brew doctor` and that did not fix my problem.

### What were you trying to do (and why)?

Install podman for Debian Linux inside of WSL.

### What happened (include all command output)?

Installing podman in Debian compiled and installed a Darwin binary.

### What did you expect to happen?

I expected to get a Linux version of the binary.


### Step-by-step reproduction instructions (by running `brew` commands)

We're a bit stuck with this one. There was an attempt to fix this earlier, but it became clear that a number of dependencies need to be added as new formula (some of them possibly Linux-only): #22227. I expect we'll eventually get this to build on Linux, but it may not be for a while.

Appreciate the feedback on this. If thats the case could podman be removed from linux installs? Or at least something that very clearly states it won't work on Linux installs?

Closing, sorry. If this issue is still relevant: please reopen on homebrew-core.
