Gem installation fails under Ruby3.2

[stell]

What problems are you experiencing?

Trying to install mailcatcher gem under rubyinstaller-devkit-3.2.2-1-x64.exe.
The instruction to install it under ruby3.2 can be seen here: sj26/mailcatcher#539 (comment)

Steps to reproduce

So when doing this:
gem install mailcatcher --version=0.9.0.beta2

I get the following:

Many of the dependencies of mailcatcher are very old. For one example, see eventmachine/eventmachine#785, which was first available in v1.2.4. mailcatcher has eventmachine locked to v1.0.9.1.

See sj26/mailcatcher#546, which should allow it to build on Windows, but it may have issues with OpenSSL 3.x. Not.Sure.

Hey, @stell. Depending on what you're up to, I created this fork to focus on improvements to the containerized service. It's totally updated but it's not a gem. Prepared to up by docker/compose. Take a look: https://github.com/dcotecnologia/mailcatcher

hi @stell - would you close this issue if there is no additional help needed? If we don't hear back by 27th, I will close this!
