There's something funny about Ruby. None of my applications uses it. I have USE = -ruby -jruby in make.conf. equery depends reports none of the application that depend on ruby. Nevertheless when I try to update world emerge installs ruby. I've allowed to install it, then removed everything manually and run revdep-rebuild. Nothing broken was found. When I try to run emerge -pvNDtu @world it gives me following output

These are the packages that would be merged, in reverse order:

As one can see, the reason why 3 versions of ruby is installed is because uninstalled package dev-ruby/json wants to have them. And that package is installed because it is needed by itself. Looks like some circular dependency.
Any way around it. Definitely I don't want to have so much of junk in my system.

Actually I've found the workaround. Adding following to package.mask solves the problem

If I had to guess I'd say it's sys-block/thin-provisioning-tools from lvm2 'thin' useflag that pulls in ruby.

No. It looks like I've figured out what was the problem. Before, I had gdm installed. When I've tried to update today I've noticed that it pulls in lots of gnome stuff and creates conflicts. So, I've uninstalled gdm. I've executed 'emerge --depclean' but for whatever reason it didn't clean up all of the packages. Then I did update and that pulled in ruby because that was new gdm dependency. Then I've run 'emerge --depclean' again and this removed few more packages.
Then I've removed ruby manually, but I've missed 'virtual/rubygems' and that was pulling ruby back in. After masking ruby I executed 'emerge --depclean' again and this time that virtual/rubygems was removed. Now I could unmask all ruby packages and they don't get pulled in anymore.

The thin-provisioning-tools is installed, but this package does not require ruby.

So, I'm marking this as SOLVED, though the 'emerge' was not very helpful in this situation, even somewhat misleading because -t option showed circular dependency where virtual packet was the culprit.

The currently stable version 0.2.8 does.
That appears to be a mistake though since 0.2.8-r1 only needs ruby for the tests.

virtual/* oddities :lol:

I hit this same issue some days ago. What I did was to create an overlay for thin-provisioning-tools and set the dependencies to just expat. I really hate when distros starts forcing random compilers down your throat. I have managed to live without java (not without fight) until now, and no one's going to force ruby or lua on me, even if that means I'll have to create a GNU/i92OS :P

I see, but I have 0.2.8-r1 without "test", that is why I don't have ruby. Interesting, I remember that it was "emerge" that requested adding thin-provisioning to the keywords file. But now I can't find any package that would require development version of it. Probably again it was one of the removed packages. Or maybe it was because all of ruby was masked :)
