It's dev-ruby/ruby-fcgi for ruby 1.9 Reproducible: Always
Argh, just noticed it - pleaase prefix the summary with the Gentoo package name in future, Shabanov.
Are you sure in your right summary? ruby-fcgi-1.9 don't exist at all. I requested bumping ruby-fcgi which for ruby-1.9 named like fcgiwrap-0.1.6.
Er, IMO you're both a little wrong. ;) fcgiwrap is an entirely different thing. It is a wrapper for CGI programs to support FCGI. (It needs ruby-fcgi to operate) ruby-fcgi still is the FCGI library. Although there is no updated release for 1.9, upstream has a compatibility patch in SVN. You'll find both packages, working with Ruby 1.8 and 1.9, in the Ruby overlay.
ruby-fcgi working with 1.9 is in-tree.
