I really hope that having to call a binary with a slightly different
name is something that the average developer can do.

And as i said this only affects a few very core binaries. all our
rubygem rpms are using update-alternatives.

Sure. Will you and your team help with the work and the maintenance
to keep it working in the long run?

This has to be done for every executable which is installed by a gem. Is there 
some more convenient way than doing that manually?

The problem with versioned binaries is that it's incovenient to type, and more 
importantly that all documentation, examples, snippets, scripts you can find 
out there are assuming non-versioned binaries. It would be nicer to have a way 
to work with Ruby which works out of the box for everybody.

Might it be possible to make YaST use a versioned version of Ruby, so that the 
system Ruby would be a bit more flexible?

as the ruby maintainer i can recommend this way if you can't live with
versioned binaries.

As Josef pointed out already do not change the system ruby.

Now if we as openSUSE project would want to have /usr/bin/ruby variable
the following things need to be done:

1. fix all shebang lines to use a version ruby path.
2. make sure all packages require the version used in their shebang
   line.
3. switch code to update-alternatives for /usr/bin/ruby.

Install the packaged version you want. Handle ruby by linking it into a 
directory that is in front of your path.


ln -sf /usr/bin/ruby.ruby$VERSION ~/bin/ruby
ln -sf /usr/bin/gem.ruby$VERSION ~/bin/gem
