You will need to have root access to do this. If you aren’t already the administrative user, login as the administrator. Then use ‘sudo’ to change the permissions: sudo chmod go-w /usr/local/bin Obviously, that will mean you can no longer install material in /usr/local/bin except via ‘sudo’, but you probably shouldn’t be doing that anyway.

You can also install gems in your local environment (without sudo) with gem install –user-install <gemname> I recommend that so you don’t mess with your system-level configuration even if it’s a single-user computer. You can check where the gems go by looking at gempaths with gem environment. In my case it’s “~/.gem/ruby/1.8”. If you need … Read more
well, that depends on the project in question. Some projects have a *.gemspec file in their root directory. In that case, it would be gem build GEMNAME.gemspec gem install gemname-version.gem Other projects have a rake task, called “gem” or “build” or something like that, in this case you have to invoke “rake “, but that … Read more
