Macbook M1 JRuby 9.4.2.0 Could not open library 'fixposix' 'libfixposix.dylib'

[reydi]

Problem

• After upgrading from jruby-9.3.3.0 to jruby-9.4.x.x, I don't seem to be able to run my Rails 7.0.4.3 app as usual
• Here's the error, seems that ffi cannot find fixposix and libfixposix.dylib, which was added in JRuby-9.4.0.0

Could not open library 'fixposix' : dlopen(fixposix, 0x0005): tried: 'fixposix' (no such file),

  '/usr/lib/libfixposix.dylib' (no such file, not in dyld cache), 
  'libfixposix.dylib' (no such file), 

• I've looked everywhere in the rbenv gem file of subspawn, homebrew/openjdk, but seems that installing new JRuby doesn't seem to automatically build the fixposix binary file to be available for the ffi to open the library required by JRuby 9.4.x.x.

• So I've tried to build it my self using byteit101/subspawn, and it was successfully built
  

• Then I go back to my rails project, try to run rspec again just to verify. But now I'm stuck here.

Question

I'm wondering if there's something I miss to configure that I have to go through all of this step..

• I've been running jruby-9.3.3.0 okay for the past couple of months with my Rails codebase.
• Works ok on Rails 3.0.6
