The bunlder package was updated to version 1.1.4, yet portage only goes up to 1.0.18/1.0.22. Renaming the ebuild is enough because from version 1.0.18 to 1.1.4 there are only bug-fix / new-features releases; I am using bundler-1.1.4 (installed by overlay) on a couple of Gentoo/Linux servers (hardened profile) serving both ruby18 and ruby19 applications and they are working flawless. Reproducible: Always
Please include the output of FEATURES=test USE=doc for all the ruby targets to confirm that it works correctly. According to our bump notes on http://wiki.gentoo.org/index.php?title=Project:Ruby/Pending_Bumps it fails tests on ruby19. Also note that we keep track of outdated gems automatically so in general there is no need to file bugs for them: http://moving-innovations.com/~graaff/outdated-gems/
bundler 1.1.5 is now in the tree.
