I've created a pull request to make it usable for Ruby 3.4 as well.

fb-0.9.3.gem is old, so please try compiling it from the latest pull request source and installing it.

Thanks, it worked. I had one problem though, after requiring the fb gem ('require fb') I got an error saying that it could not found the gem "bigdecimal" even having it installed, I had to copy the file "bigdecimal.rb" into the folder where the fb.c file is and it worked. This is in Windows 11.
