Upstream tells that ruby-dbi should support ruby 1.9 since 0.4.1: http://rubyforge.org/forum/forum.php?forum_id=28741 But our ruby-dbi-0.4.3.ebuild doesn't support ruby19.
Feel free to test with ruby19 and provide a build log for it (with FEATURES=test and USE=doc), and I'd be happy to add ruby19 to the ebuild.
Created attachment 326586 [details] build.log for test failures against ruby19 Most of errors look like that: > Error: test_accessors(TC_DBI_ColumnInfo) > RuntimeError: can't add a new key into hash during iteration
So basically this is a wontfix until you can get this fixed. Which I doubt will ever happen, standing to dbi's history.
