Description Cheng 2010-01-23 17:39:36 UTC

`emerge eventmachine` failed. It seems eventmachine-0.12.10 was fine, but 0.12.10-r1 was not.


Reproducible: Always

Steps to Reproduce:
1. emerge eventmachine -up
Actual Results:  
These are the packages that would be merged, in order:

Calculating dependencies... done!

Either use rake from ~amd64 or don't use eventmachine from ~amd64, see http://blog.flameeyes.eu/tag/rubyng for the whole story behind this, but you're now getting part of the packages from the new interface and part from the old, which is not going to work.

I try to install the ruby web server `thin`, and a similar error occur.

 Missing IUSE: ruby_targets_ruby18

What is it anyway? Here is the emerge log:

emerge: there are no ebuilds built with USE flags to satisfy ">=dev-ruby/daemons-1.0.9[ruby_targets_ruby18]".
!!! One of the following packages is required to complete your request:
- dev-ruby/daemons-1.0.10 (Missing IUSE: ruby_targets_ruby18)

(dependency required by "thin" [argument])

Hello Diego:

How to resolve the problem happens to `thin`. I don't get a clear idea from the blog.

You're mixing stable and non-stable, so you're going to get problems. Just use _all_ the Ruby packages from unstable if you want some, as we're transitioning to a new system.
