[gentoo-user] installing ffi gem
I've just tried setting up a new development machine and I'm stuck installing the ffi gem for ruby. According to a bug I found (can't find it now I'm afraid) the gentoo devs do not support installing gems via the gem command and directed the user to use the dev-ruby/ffi package. Unfortnately, that package is absolutely ancient and unusable. Anyway, I've got the ffi library install from portage, but when I try to `gem install ffi`, I get the output seen in the attachement. The same gem installs just fine on an ubuntu box, but...well it's ubuntu and I don't want to use that (besides it's just a VM). I'd really like to get this fixed so I can get started on a new project.

Re: [gentoo-user] installing ffi gem
Apparently, though unproven, at 01:57 on Friday 22 April 2011, Matt Harrison did opine thusly: I've just tried setting up a new development machine and I'm stuck installing the ffi gem for ruby. The gentoo dev most active with ruby gems is flameeyes. He's a prolific blogger and documents everything he is going through in full painful detail here: http://blog.flameeyes.eu The most current info on how to deal with gems on gentoo will be found there IMHO According to a bug I found (can't find it now I'm afraid) the gentoo devs do not support installing gems via the gem command and directed the user to use the dev-ruby/ffi package. Unfortnately, that package is absolutely ancient and unusable. Anyway, I've got the ffi library install from portage, but when I try to `gem install ffi`, I get the output seen in the attachement. The same gem installs just fine on an ubuntu box, but...well it's ubuntu and I don't want to use that (besides it's just a VM). I'd really like to get this fixed so I can get started on a new project. Grateful for any help Matt -- alan dot mckinnon at gmail dot com

That way you leave the system Ruby alone and can develop with the versions you want. You can even do multiple versions of ruby and various gems for working on many different projects at once. https://rvm.beginrescueend.com/rvm/install/ It really is the simplest way to build a dev environment and maintain it for Ruby. kashani
