At the time this report is being filed, prefix requires gorg to be keyworded, and only offers 0.6.4-r1, which has been outdated since 26 Oct 2012 and was removed on 25 Dec 2013 from the main tree. Jumping through the hoops to get 0.6.4-r1 built (including getting the source as a zip archive from GitHub since the tgz referenced in the ebuild isn't available anymore), I get the error $ gorg Gorg::init failed: Could not parse config file: undefined method `each' for #<String:0x007faeab87d708> With any luck, if the current latest version (0.7.1) is prefixified this bug will go away.
