rugged does not seem to work with TruffleRuby

[mtortonesi]

In my quest to get the bake-modernize gem working with TruffleRuby, I found out that rugged does not seem to work with TruffleRuby (version truffleruby+graalvm-23.0.0 installed from rbenv+ruby-build on an M1 MacBookPro):

Would like to help fixing the issue, but don't know where to start. Any suggestion?

Should be fixed with dev build as you found in https://github.com/oracle/truffleruby/issues/3208

I can confirm. The latest version of TruffleRuby works perfectly.
