I was working with buildr, which requires rjb. I use RVM to manage my rubies, and I used: rvm use 1.8.7 rvm gemset create buildr rvm use 1.8.7@buildr gem install buildr buldr I then got: [BUG] cross-thread violation on rb_gc() (null) zsh: abort buildr Long story short, when you uploaded the gem, it looks like you compile it against the runtime version of Ruby that comes with Mac OSX. That's not going to work for any rubies that are compiled under RVM. To fix the problem, all I had to do was download rjb, unzip it, cd into it, and while still in the same rvm gemset, run your installation steps for unix (minus the sudo, obviously). I could then run irb and "require 'rjb'" without issue. Thus, I would highly recommend that you break out the windows and mac-specific gems into their own sub-gems. Or, perhaps create a 'rjb-source' gem that just runs extconf.rb on install. Thanks, great work. -Gabe

It will install correctly then. -you can do a gem install, forcing to use a particular distrib of rjb. Buildr 1.4.7 will fix this problem.

It's headache gem's behavior (it didn't check for the library version of Windows's gem, but it seems latest gem checks correctly), although general speaking, people like to install gem without compilation especially on Windows, also OSX users who don't want to install XCode. That's because I can't remove platform specific gems from the repository. It seems very nice your suggestion 'rjb-source'.gem. But at this time, it's not permited by rubygems.org (see below), so I may mind your suggestion for the next release time. Thank you. ---------- $ mv rjb-1.3.4.gem rjb-source-1.3.4.gem $ gem push rjb-source-1.3.4.gem Pushing gem to RubyGems.org... Repushing of gem versions is not allowed.
