Gentoo - install Ruby 1.9.2 - resolve problems with ruby_targets_ruby19

Gentoo - install Ruby 1.9.2 - resolve problems with ruby_targets_ruby19

Lastly I faced problems with installing Ruby 1.9 on Gentoo distros. First I unmasked Ruby 1.9.2 version. I use for that autounmask tool:

# autounmask =/dev-lang/ruby-1.9.2

But after that I received error on rdoc installation:

# emerge ruby
emerge: there are no ebuilds to satisfy ">=dev-ruby/rdoc-2.5.11[ruby_targets_ruby19]". (dependency required by "dev-lang/ruby-1.9.2" [ebuild]) (dependency required by "ruby" [argument])

How to resolve that problem and install Ruby 1.9?

First you should add ruby19 RUBY_TARGETS in /etc/make.conf

(add line in /etc/make.conf)
RUBY_TARGETS="ruby18 ruby19"

Then unmask Ruby target for 1.9 version (really strange):

# echo "-ruby_targets_ruby19" >> /etc/portage/profile/use.mask

After that you need to run again autounmask tool for unmasking all needed packages for added target Ruby 1.9:

# autounmask =dev-lang/ruby-1.9.2

I know that this is very unintuitive but it's how things working now in portage for USE flags unmasking. That all you should have Ruby 1.9 installed and ready to work.
