The beauty of mise is that as long as someone is hosting a precompiled binary for you, it's easy to get it. I just repro'd and yeah, `mise use php` fails for me on my machine because I don't have any dev headers. But looks like there's an easy workaround using the `ubi` downloader:

or see the first comment on this thread to see a way to explicitly specify where to find the binaries for each platform:

Having these kind of "eject" options is one of the reasons I really appreciate Mise. Not sure this would work for you but I'd rather be able to do this than have to manage/support everyone on my dev team installing and maintaining Nix.
