In Ruby 2.2.2 I used to be able to refer to a gem's source directory in Gemfile, for example "/Users/david/programs/weaver", and Gem.datadir would return the data directory in that dir "/Users/david/programs/weaver/data/weaver".

However that changed in Ruby 2.3, after changing to Ruby 2.3, all of a sudden it started returning a different directory: "/Users/david/programs/gems/weaver-0.3.4/data/weaver"

The "gems" directory does not (and should not) even exist, and I never created one, and the output of pwd when checking Gem.datadir is "/Users/david/programs/weaver-doc-source"

I have checked the changelogs and could not find any mention of changes to the Gem class that should affect this

This seems like a piece of debug code has made it into the Gem class.

This is not apparently a bundler issue since it does not happen with either the version of bundler I used or the latest version of bundler. The Ruby version is the only variable of consequence here.
