gem install mimemagic -v '0.3.10' fails to install on Big Sur

Question

Mac OS Big Sur 11.4

** Rails 6.1.0 ** however, my use case is for a Rails Engine that I am writing that targets Rails 6.1+ applications

xcode-select version 2384.

GCC version % gcc -v Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1 Apple clang version 12.0.5 (clang-1205.0.22.11) Target: arm64-apple-darwin20.5.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin

the gem I am trying to install is

mimemagic 0.3.15 installed with bundler Bundler version 2.2.19

this is in a non-Rails application that uses bundler. in my app mimemagic is resolving (new) to 0.3.5, but won't install on Mac OS Big Sur

gem install mimemagic -v '0.3.10' --source 'https://rubygems.org/'

the result is

Building native extensions. This could take a while... ERROR:  Error

Ensure you have either installed the shared-mime-info package for your
distribution, or obtain a version of freedesktop.org.xml and set
FREEDESKTOP_MIME_TYPES_PATH to the location of that file.

This gem might be installed as a dependency of some bigger package,
such as rails, activestorage, axlsx or cucumber. While most of these
packages use the functionality of this gem, some gems have included
this gem by accident. Set USE_FREEDESKTOP_PLACEHOLDER=true if you are
certain that you do not need this gem, and wish to skip the inclusion
of freedesktop.org.xml.

The FREEDESKTOP_PLACEHOLDER option is meant as a transitional feature,
and will be deprecated in the next release.
