Bug #15407
closed
bundle, bundler, irb, rdoc, ri commands broken if --program-suffix configure option is used
Description
With recent changes to tool/rbinstall.rb, if you use --program-suffix (or a similar option),
it will result in bundle, bundler, irb, rdoc, ri not working, because they try to load a
file from the gem directory which has been modified with the same suffix.

Traceback (most recent call last):

These LoadErrors happen because ruby when configured with the --program-suffix option
installs the irb gem exe file as /usr/local/lib/ruby/gems/2.6/gems/irb-0.9.6/exe/irb26
(with similar issues for other default gems with executables).
Attached is a patch that modifies tool/rbinstall.rb so that the files in the gem directory
are not renamed on install. I'm not sure whether this patch causes other issues, but I can
confirm it does fix the problem described if --program-suffix is used.
